A high-purity aluminum plating is commercially available for corrosion control. The coating can be applied via a wet but non-aqueous process to any conductive substrate, from carbon steel to aluminum beryllium alloys and even graphite. The process is compliant with existing military aluminum plating specifications and has been qualified by a number of aerospace OEMs. High-purity aluminum has excellent corrosion resistance properties, even as a thin coating. It is also highly ductile, non-embrittling, mitigates galvanic corrosion and can be used in applications up to 1000 deg F. The plating process will be introduced and several applications will be discussed, including cadmium substitution, high-strength and embrittlement-sensitive components, elimination of galvanic corrosion with aluminum assemblies, and replacement of ion vapor deposited aluminum.
