What is AMS 2438?

AMS 2438 is the current standard for thin dense chrome plating, specifying requirements for durability, wear resistance, and consistent performance in demanding applications. It was developed by the Society of Automotive Engineers (SAE) through its Aerospace Material Specifications (AMS) B Finishes, Processes, and Fluids Committee. It outlines key performance criteria that may vary by coating and application, including deposit characteristics such as thickness, hardness, adhesion, and uniformity.
Initially created for aerospace parts, AMS 2438 has evolved to incorporate advancements in materials and manufacturing. It also includes testing protocols to assess coating quality and ensure reliable performance across different industries. While it remains essential in aerospace, it's also widely used in automotive, medical, and industrial equipment. By following AMS 2438, manufacturers achieve reliable, high-quality chrome coatings that meet strict industry standards.

AMS 2438 Testing Methodology & Results

AMS 2438 outlines numerous tests to assess the quality, durability, and performance of thin dense chrome plating. While specific tests vary by application, common periodic tests include:

  1. Hardness Test: Measures resistance to deformation under pressure using microhardness testing techniques, ensuring it can withstand mechanical stress.
  2. Adhesion Test: Confirms strong bonding to the substrate to prevent delamination or failure.
  3. Corrosion Resistance Test: Assesses protection against harsh environments using salt fog or porosity tests.
  4. Abrasion Resistance Test: Evaluates wear resistance through methods like the Taber Abrasion Test.
  5. Hydrogen Embrittlement Test: Ensures the component resists brittleness caused by hydrogen absorption.

AMS 2438 upholds strict quality assurance through sampling, periodic testing, and precise documentation to maintain consistent plating performance.
