Cadmium Plating Processes

Cadmium Plating Processes

Cadmium Plating Processes

(OP)
What is the process for "Vacuum Deposit" Cadmium Plating and is there a benefit to this process over the other? There seem to be a limited number of facilities that do this.

RE: Cadmium Plating Processes

The most obvious advantage is compete freedom from hydrogen embrittlement.Process involves putting the part in a vacuum chamber and volatilizing the cadmium. I seem to recall that the cad is heated somewhat to help it volatilize.

RE: Cadmium Plating Processes

swall gave you the product benefit.  The process benefit is reduced environmental problems.  The vacuum process is fully contained, so no wastewater contamination, hazardous emissions, etc.

RE: Cadmium Plating Processes

Two specifications for the process are AMS 2426, and AMS-C-8837, the word-for-word copy of Mil-C-8847, which is still available on ASSIST.
