In order to meet the demand of cadmium substitution for civil aircraft, the differences of galvanized nickel process requirements in Boeing, Airbus, Bombardier and other famous aircraft manufacturer were analyzed, and the NZ - 70 series alkaline galvanized nickel solution electroplating samples widely used in China were tested. Results showed that NZ - 70 galvanized nickel solution could meet the enterprise requirements of Boeing, Airbus, Bombardier, and American aerospace material specifications for galvanized nickel adhesion, corrosion resistance, nickel content, hydrogen embrittlement. In addition, the hydrogen leakage of the coating was not lower than the performance requirements of cyanide cadmium and titanium plating, which could replace the imported solution for the surface protection of high - strength steel parts of civil aircraft.
