Abstract

WC-8Co and Nak80 is deposited on the surface of 45 steel by DZ-4000( ) multifunctional surface hardening machine what use argon as shielding gas. By means of changing the order of WC-8Co and Nak80 electrodes’ deposition and different of roughness of Nak80 coating’s surface, thesis analyzes the effects what the freezing point and roughness have on composite coating thickness and topography as well as morphology of cross-section. The result shows that: only when WC-8Co electrode deposits (the WC-8Co’s freezing point is higher than Nak80’s) on surface of Nak80 coating which roughness is prodigious, the matrix cannot fasten the prill of WC-8Co what concretionary first and the splashing prill also takes Nak80 away what leads to bring the composite coating thickness down.
