Titanium nitride or carbonitride coated copper component - used esp. in resistance or arc welding or in electrical switches

摘要

A copper-based component, with a titanium nitride or carbonitride coating, is new. The coating is pref. 1-10 (esp. 1.5-4) microns thick. Prods. of the component involves opt. plasma-assisted, PVD or CVD. USE/ADVANTAGE - The component may be a resistance spot, roller seam or projection welding electrode, a component (esp. shielding gas nozzle, electrode clamping sleeve or wire contact nozzle) of a TIG or MGA welding torch or a component of an electrical switch element.
