The Characterization of W-Cu Composite Coating Prepared by Double-Glow Discharge
In this paper, a W-Cu composite coating was prepared on the Cu substrate through the double-glow discharge technology using a pure W plate as a target. In here argon gas was input into the chamber as the discharge and sputtering gas. The crystal composition and microstructure of W-Cu composite coating were examined by x-ray diffraction (XRD), scanning electron microscopy (SEM). The compose in the cross section was detected by energy dispersive spectrometer (EDS), the distribution of elements along the penetration thickness was then obtained. Then the friction coefficient, the polarization electrochemical corrosion test and the mi-crohardness of W-Cu composite coating was measured. The results indicated that a thick and no-delaminated W-Cu composite coating could be prepared on the Cu substrate by the double-glow plasma technology.
