ElectroSpark Deposited Coatings for Replacement of Chrome Electroplating

Abstract

Electrospark Deposition (ESD). Process Summary: A micro-welding process that uses short-duration, high-current electrical pulses to deposit an electrode material on a metallic substrate. Coating is fused (true metallurgical bond) to substrate with such a low total heat input that the bulk substrate material remains at or near ambient temperature. Rapid solidification produces nano-structures with unique tribological and corrosion performances. Coatings of nearly any electrically conductive metal, alloy, or cermet can be applied to metal or cermet substrates.
