What is AMS 2460?
AMS 2460 is a specification from the SAE Aerospace Material Specifications (AMS) Committee that defines the requirements for electrodeposited chromium plating. This standard is widely used in aerospace, automotive, and commercial industries, ensuring plated components meet stringent performance and aesthetic requirements. The current revision, AMS 2460B, is based on similar requirements to the now-canceled AMS-QQ-C-320B but is generally more stringent.
The standard categorizes chromium plating into two main classes:
Class 1 - Decorative: Used in applications where corrosion protection and visual aesthetics are key. These coatings are typically thinner and available in bright (Type I) and satin (Type II) finishes. Testing focuses on surface appearance and corrosion resistance.
Class 2 - Engineering: Designed for functional performance in high-stress or wear-intensive environments. This type of plating is thicker and harder, offering wear resistance, reduced friction, and abrasion protection. Testing emphasizes mechanical integrity and durability.
AMS 2460 provides precise specifications for plating thickness, adhesion, and surface finish, balancing form and function to meet the needs of diverse applications.
The Role of AMS 2460 in Electrodeposited Chromium Plating
AMS 2460 sets the industry standard for hard chromium plating, ensuring components meet the highest quality, durability, and performance levels. Its key contributions include:
- Defining Quality Standards: Covers tests for coating thickness, adhesion, hardness, surface finish, porosity, and other factors for consistent, high-performance plating.
- Maximizing Wear Resistance: Produces tough, abrasion-resistant coatings that extend component lifespan in demanding conditions.
- Balancing Form and Function: Combines durability and wear resistance with a refined surface finish, supporting both practical and aesthetic requirements.
- Supporting Industry Compliance: Aligns with industry specifications and certification requirements, streamlining approval processes.
AMS 2460 provides the technical foundation for high-performance chromium plating, guiding manufacturers in producing coatings that meet the toughest operational demands.
AMS 2460 Testing Methodology & Results
AMS 2460 includes a variety of tests to confirm that chromium plating meets functional and aesthetic requirements. Some of the tests performed under AMS 2460 include:
- Thickness Test (Class 1 & 2): Verifies the coating’s thickness to ensure it meets AMS 2460 specifications for both decorative and functional applications.
- Adhesion Test (Class 1 & 2): Confirms the coating is bonded to the substrate.
- Hardness Test (Primarily Class 2): Measures the plating’s hardness to confirm its resistance to deformation.
- Visual Inspection (Class 1 & 2): Assesses surface appearance for uniformity, brightness, and other aesthetic or functional needs.
- Porosity Test (Primarily Class 1): Evaluates the coating for microscopic pores that could allow corrosion.
- Hydrogen Embrittlement Test (Class 2 only): Confirms the plating process does not weaken high-stress components due to hydrogen absorption.
Additional tests may apply based on the application and material, helping deliver consistent quality and performance whether used for decorative or engineering purposes.
Industries that Follow AMS 2460
AMS 2460 is vital for industries that rely on high-quality chromium plating for functional and decorative applications. Key sectors include:
- Aerospace: Used for critical components such as landing gear, engine parts, and hydraulic systems.
- Automotive: Ensures corrosion protection, aesthetic finishes for trim pieces, and wear resistance for engine and transmission components.
- Defense: Provides durable coatings for military equipment and weaponry.
- Oil and Gas: Protects drilling equipment, valves, and pipelines from harsh environments.
- Injection Molds: Enhances the longevity and performance of molds, dies, and other precision tools.
These industries depend on AMS 2460 to ensure their components meet durability, performance, and appearance requirements.
