Plating / Coating for SmCo
Plating / Coating for SmCo
(OP)
Hello, All:
I would appreciate any input for the following-
I have SmCo magnets operating at 350c and under vacuum. Our concern is out-gassing and I do not know of a plating or coating which will prevent the out-gassing and stay intact for the few years of service required. We would typically use Nickel or Paralyne, but the temperature seems too high. (Micro-fissures in the Ni and operating temperature of Paralyne N does not make it.)
I would appreciate any and all comments.
Thank you,
Mac

Some people here are fearful because we have not quantified the degree of out-gassing. So we are somewhat executing a preventative action as insurance. The vacuum we intend to pull is 1x10^-4 Torr.
Thank you for the reply.

SmCo material is sintered, nearly 99% dense. If the vacuum level is 1x10^-7 or less there might be an issue.
One other point: It is very difficult to metallic coat SmCo, although it can be done.

I really appreciate the input.

We had customers that wanted this done. We then packaged the warm magnets in ziplock bags.
