Beyond the Surface: Exploring the Science and Benefits of Nadcap Cadmium Plating for Wear Protection

Nadcap cadmium plating is the process of applying a layer of cadmium onto a metal substrate to enhance its corrosion resistance. This plating method is certified by Nadcap, an accreditation program for defense and aerospace industries. It verifies that the plating process adheres to specific technical requirements and industry best practices established by regulatory bodies.

This article will examine the key characteristics of this Nadcap cadmium plating, including its advantages and the quality control measures enforced by Nadcap certification.

The Science Behind Nadcap Metal Plating

Nadcap plating involves a scientifically precise process of depositing a metal layer onto a substrate. This plating technique relies on electroplating, where an electric current reduces dissolved metal cations to form a coherent coating. In the case of cadmium plating, the substrate is the cathode, whereas cadmium ions act as the source of the plating material.

The science behind Nadcap cadmium plating includes material properties and surface chemistry considerations. Cadmium a relatively rare transition metal offers excellent corrosion resistance that is ideal in harsh environments such as aerospace applications. Its ability to form a stable oxide layer further enhances its protective properties.

Benefits of Nadcap Cadmium Plating

Here are the key advantages of this specialized cadmium plating technique:

Corrosion Resistance

Cadmium forms a protective oxide layer on the substrate’s surface, shielding it from corrosion caused by moisture, salt, and other corrosive agents. This makes it particularly valuable in aerospace and defense applications where components are exposed to extreme conditions.


Cadmium plating offers a durable coating that can withstand mechanical stress, abrasion, and temperature variations. This durability ensures the longevity of parts and components, reducing the need for frequent maintenance and replacement.


The lubricating effect helps minimize frictional losses and prevents seizing or galling of components. This property is highly advantageous in manufacturing fasteners, bearings, and gears, where smooth operation and extended service life are essential.

What Is Nadcap Certified for Chemical Processing?

The Nadcap accreditation is an industry-driven program in which highly qualified industry experts perform operating evaluations using process-specific criteria. It is administered by the Performance Review Institute (PRI), allowing it to establish stringent standards for chemical processing, including metal plating.

The process assessment of Nadcap ensures that all critical component processing, safety checks, and testing are carried out following standard procedures. It also includes recording, storing, and furnishing essential information per specification. This is accomplished by conducting stringent and in-depth audits on parts from receiving requests to final inspection.

What Is the Process of Obtaining Nadcap Certification?

Almost every aerospace prime and their major suppliers all over the globe now require Nadcap accreditation as a prerequisite for doing business. This prompted Nadcap to offer programs for testing labs, non-destructive diagnostics, heat treating, surface coating, chemical processing, and other applications.

To qualify for the Nadcap review, companies must possess a quality system certification — such as the AS9100 — or acceptable equivalents from a recognized third-party advisory committee. Suppliers who do not have the necessary quality system certification can add an extra audit day with the PRI to achieve the AC7004 aerospace quality system audit or the AC7006 laboratory audit.

Once a company officially requests an audit for a Nadcap certificate, it must follow a few steps. First, the audit will be arranged and scheduled, and the company will be assigned an auditor. Next, any non-conformity issues will be brought up, and non-conformance findings and reports will be issued after the audit. The PRI will then close out the non-conformance reports and submit the completed audit package to a task group, which will review it and vote on its approval.

Nadcap task groups are made up of individuals — prime contractors, government representatives, and suppliers — who are considered experts in the product, process, or service for which companies are to be audited. Their responsibilities for the accreditation program include the following:

  • Implementing the accreditation process
  • Recommending auditor hiring and training needs
  • Developing standards and checklists
  • Creating performance measures, metrics, and quality improvement

Lastly, when all non-conformances have been resolved, accreditation is granted to the company or supplier. The enterprises that have been given the auditing approval will gain new perspectives on their operational processes and a summary list of areas for improvement. Everything from system escapes to field failures is avoided through thorough assessment and methodical change, resulting in reduced part cost and process variability.

What Are the Best Preparation Techniques for a Nadcap Certification?

The Nadcap process assessment is a complex and time-consuming procedure. Often, the most difficult step is knowing where to begin. Here are a few techniques for adequate auditing preparation:

Identifying Key Documents and References

A recommended first step in preparing for an audit is to know which documents to refer to and which requirements to follow throughout the audit. Several websites provide useful information about Nadcap.

PRI gives access to various supplemental materials for reference during the Nadcap audit. These include documents on pre- and post-audit processes, detailed information on response timeframes, how to reduce the frequency of audits, what to do in the event of a failed audit, and other topics.

Consulting With Other Suppliers and Companies

Consultation with other suppliers can aid in exploring best practices for audit preparation. Attending at least one of PRI’s three annual meetings is one opportunity to discuss others’ audit experiences. If you cannot participate in a PRI meeting, you can read the meeting notes, which contain information on the discussions and decisions made on particular issues and guidelines.

Discussing other companies’ Nadcap audit experiences can benefit a company because it provides exposure to different points of view to better understand the process. Furthermore, constructive conversations about best practices and proposed methods contribute to better regulation and ensure consistent adherence to global quality standards.

Scheduling the Nadcap Audit

The official Nadcap audit can be scheduled via the official website following a thorough review of the relevant documents, reference materials, and other auditing notes. It is suggested to know the answers to the following questions:

  • During the audit, will you run real orders for an aerospace client or sample parts?
  • Have you identified the accreditation scope for which you wish to be audited?
  • Do you already have an approved quality system?
  • Have you allotted enough time to plan for and conduct an internal audit?

Understanding the Internal Audit Procedure

Knowing the specific internal audit requirements is crucial to preparing for the official Nadcap audit. Internal audits include quality system audits (such as AS9001 or AC7004) and live job audits. These include reviewing past surveys, system accuracy tests, leak assessments, maintenance logs, and historical jobs.

What Are the Advantages of Working With a Nadcap-Certified Company?

Obtaining a Nadcap certification is currently a challenge for small businesses. Many suppliers opt not to be accredited, either by declining audits after initial accreditation or by never becoming certified in the first place.

Audits can be costly, and committing to constantly evaluating processes and trying to manage audit tasks throughout the year can be time-consuming. Moreover, it can be a significant financial investment to update processes and procedures and a substantial time dedication for staff training and quality management.

As a result, finding a company that has gone through the process assessment is critical, as the primary goal of Nadcap is to ensure and sustain high-quality, standardized business practices that benefit both the company and its customers.

Here are other advantages that a Nadcap-certified company can provide you with:

  • Confirmed adherence to best practices

Why Choose Cadmium Plating?

Cadmium is a versatile metal used in various industrial applications, including batteries, alloys, and pigments, with electroplating being the most common. Although it is highly toxic and should not be used on surfaces that come into direct contact with food, cadmium provides superior protection to industries constantly subjected to harsh conditions.

In this article, we will walk you through the fundamentals of cadmium plating, including its process, benefits, applications, and types.

What Is Cadmium Plating?

Cadmium plating, also referred to as cadmium electroplating, is a type of metallic coating with distinct and advantageous properties. In this process, cadmium undergoes electrodeposition onto the metal from a formula with electrolytes and cadmium salts in vats or barrels. These electrolyte solutions are based on the cyanine alkaline system. However, there are other solutions, such as fluoroborate-based systems, but the results may need more brightness and power.

Another method is mechanical cadmium plating, which uses mechanical energy to apply coatings to components. This application is ideal for clips and fasteners that are small enough to be plated within a barrel. Finally, this process can be carried out using ion or vacuum deposition, in which cadmium is heated inside until it vaporizes. The process is followed by condensing cadmium atoms, forming a thin film of high-quality coating as its by-product.

Benefits of Cadmium Plating

Cadmium plating is a sacrificial coating, which means it corrodes and degrades before the underlying material, providing a layer of protection to the metal below. Furthermore, it offers several advantages, including the following:

  • High resistance to saltwater corrosion
  • Provides adhesives with an exceptional bonding surface
  • Excellent electrical conductivity
  • High solderability level
  • Built-in lubricity, which prevents galling and yields a low-friction surface
  • Natural resistance to mold and bacteria
  • Can coat dissimilar materials, complex shapes, and difficult-to-reach contours with ease
  • Applicable in an ultra-thin, lightweight layer

Industries & Applications of Cadmium Plating

Cadmium electroplating is used in several industries, including:

Military and Aerospace

Cadmium electroplating’s anti-corrosive properties and natural lubricity make it ideal for critical in-flight applications. In addition, its adhesive properties make it particularly useful for bonding materials to aircraft aluminum frames.


Cadmium plating is commonly found in disc brakes and hoses in modern high-performance automobiles, tractor-trailers, and other modes of transportation because of its corrosion resistance.


Cadmium plating has excellent resistance against saltwater corrosion, making it ideal for marine applications.


Cadmium electroplating’s conductivity makes it an ideal choice for electronic connectors and relays. It is also used to manufacture batteries for cell phones and laptops.

Construction and Manufacturing

Cadmium coats many standard components in industrial construction, such as hardware and industrial fasteners. It is also present in prefabricated products used in various manufacturing environments.

Types of Cadmium Plating

The post-treatment colorization of cadmium coating is referred to as the plating type. Cadmium plating comes in three different types and classification levels, which are as follows:

Type I

Type I, also referred to as “as plated,” is the standard color scheme for cadmium plating. Therefore, no additional color treatment has been applied to this type.

Type II

This type of cadmium plated is iridescent yellow. The quality of this treatment is evaluated by spraying salt on the exterior of the plated component and then inspecting for corrosion after a 96-hour waiting period.

Type III

This cadmium plating is used as a paint base and has a supplementary phosphate colorization.
