A technology for the cold spraying of copper that produces better results than traditional ultra-thick or heavy electroplating of copper has reportedly been developed by ASB Industries, Barberton, Ohio. The system produces no oxides during the process, resulting in a higher quality coating and better electrical conductivity.

Cost is also reduced, and delivery time is faster because of shorter production cycles. In one case, cold spray reduced production time from two weeks to a few hours. Because the process is cold, the original sprayed material has the same micro structure after ...
