The electrodeposited cadmium coating used to prevent corrosion of screws can cause hydrogen embrittlement type failures. Protective coatings applied to screw by processes other than electrodeposition were tested for corrosion resistance 5 salt spray test. The corrosion resistance of cadmium plated screws was significantly superior to the other coatings selected as possible candidates for replacing cadmium.
