The Properties of W Coatings on Cu by Supersonic Plasma Spray
Coatings of W on the substrate of oxygen-free Cu have been made by a high efficiency supersonic plasma spray system with a maximum power of 80kW and a maximum working at 6 m3/h flow of gas, and being compared with results of subsonic plasma spray. The bonding strength and thermal shock resistance of the coatings was tested. W/Cu functionally graded coatings is compared with single coatings of W.
