The low hydrogen embrittlement alkaline Zn-Ni plating when post treated with a trivalent chromium conversion coating is intended as a cadmium and hexavalent chromium free plating process to provide corrosion resistance on steel aerospace components. The process can be used on lower strength steel alloys, corrosion resistant steel alloys, and copper based alloys. This process is non-embrittling to high strength steels and can meet the requirements for a non-embrittling process per ASTM F519. The deposit consists of a uniform zinc-nickel alloy containing 12-15 percent nickel. It has excellent heat and corrosion resistance, especially in high temperature applications.
