Cold-spray alternative to electroplating. (Technology Trends).

A new cold-spray technology is said to speed production and improve part quality versus ultrathick or heavy electroplating of copper.

The process, introduced by ASB Industries, Barberton, Ohio, produces a high-quality surface coating with good electrical conductivity. The company says the process also shortens production cycle times--in one case from two weeks to just a few hours.

In tests on an aerospace component, the copper coating withstood temperatures from 1,800[degrees]F down to the temperature of liquid nitrogen. There were no failures of the surface material. …
