What is AMS 2406?
AMS 2406 is the industry standard for electrodeposited hard chromium plating, defining thickness, hardness, adhesion, and uniformity requirements. Developed by the SAE Aerospace Material Specifications (AMS) Committee, it ensures plated components deliver lasting performance in demanding applications.
Initially designed for aerospace components, AMS 2406 has become a trusted reference for industries requiring hard chrome plating to enhance tool and die life, maintain gauge accuracy, and restore worn or undersized parts. It emphasizes functional attributes, focusing on coating quality and performance rather than appearance.
The Role of AMS 2406 in Hard Chromium Plating
AMS 2406 establishes a structured framework for producing high-quality hard chrome coatings. Its key roles include:
- Defining Quality Standards: Sets requirements for thickness, hardness, and adhesion to ensure consistent plating performance.
- Enhancing Wear Resistance: Supports coatings with low friction, anti-galling properties, and extended durability for demanding applications.
- Mandating Testing: Requires thickness measurements, adhesion tests, and other evaluations to verify coating integrity.
- Promoting Industry Compliance: Aligns with aerospace, automotive, and defense regulations, streamlining certification processes.
AMS 2406 provides a clear roadmap for achieving durable, high-performing hard chrome coatings used in mission-critical applications.
AMS 2406 Testing Methodology & Results
AMS 2406 mandates the following tests to confirm that hard chromium plating meets high standards for quality and performance:
- Hardness Test: Evaluates the coating’s resistance to wear and deformation.
- Adhesion Test: Verifies the coating is securely bonded to the substrate.
- Corrosion Resistance Test: Tests the coating’s ability to handle corrosive environments.
- Thickness Test: Confirms the plating meets the required thickness for durability.
- Hydrogen Embrittlement Test: Ensures the plating process doesn’t weaken the component.
- Visual Inspection: Ensures the coating is smooth and evenly applied
These tests guarantee that AMS-compliant coatings deliver reliable performance in demanding conditions.
Industries that Use AMS 2406
AMS standards are essential for industries that require durable, high-performance hard chromium plating. Key sectors include:
-
- Aerospace: Used for landing gear, engine parts, and hydraulic systems to improve wear resistance and reliability.
- Automotive: Enhances engine parts, transmission components, and hydraulic cylinders for longer service life.
- Oil and Gas: Protects drilling equipment, valves, and pumps from wear and corrosion in harsh environments.
- Defense: Ensures durability and precision in military hardware and weaponry.
- Machinery: Used for hydraulic cylinders, mining equipment, and construction machinery subject to heavy wear and tear.
These industries depend on AMS 2406 in applications that require high wear resistance, low friction, and anti-galling properties.
