Aerospace series - Cadmium plating of steels with specified tensile strength ≤ 1 450 MPa, copper, copper alloys and nickel alloys

This document establishes technical requirements for cadmium electroplating applied to steel, copper, copper alloys, and nickel alloys utilized in aviation contexts, specifically targeting materials with a tensile strength not exceeding 1,450 MPa. The scope covers the preparation of surfaces, the deposition process itself, and subsequent treatment procedures to ensure optimal coating performance. It defines the necessary thickness limits, adhesion characteristics, and corrosion resistance criteria essential for maintaining structural integrity under operational conditions. Detailed specifications are provided regarding the permissible defects, such as blisters or cracks, and the procedures for testing coating uniformity. The standard outlines the methods for inspection and verification to confirm compliance with the established parameters for safety-critical components. It serves as a reference for manufacturers and quality assurance teams involved in the production and maintenance of aerospace parts where such coatings are mandated to prevent corrosion and extend component lifespan without compromising mechanical properties due to hydrogen embrittlement risks associated with high-strength materials.
