GB/T 13322-1991 "Metal Overlay, Low Hydrogen Embrittlement Cadmium Titanium Platings" standard specifies the requirements and methods for mass inspection of high-strength steel parts with low hydrogen embrittlement Cadmium Titanium plating. The standard applies to mass inspection before and after plating, including the appearance, thickness, bonding strength, corrosion and hydrogen embrittlement performance of platings. Platings should meet the requirements of cleanliness, integrity and uniformity, and the thickness of platings needs to be measured according to regulations. Hydrogen embrittlement performance inspection includes durable test and hydrogen measurement test to ensure that platings are not prone to brittle fracture under high strength conditions. The standard also details the specimen preparation, instrument calibration and test procedures, providing a comprehensive inspection basis for platings mass.
