摘要
Abstract
(Cu, Ni) solid solution based composite coating was successfully deposited on surface of Al alloy ZL104 via laser cladding process on the basis of metastable liquid separation in Cu-base melt. The composite was reinforced by in situ spherical particles. Friction and wear test of the coating was made.The results show that the (Cu, Ni) solid solution has cellular and dendritic microstructure, while the spherical particles have granular, spike or leafy substructure. The laser clad composite coatings greatly improve the wear properties of Al alloy ZL104. This contributes to high hardness of the composite and existence of the reinforced spherical particles, and also to poor mutual solubility of Cu and Fe. During the friction and wear test, ZL104 alloy mainly undergos adhesive wear and delamination while the laser clad composite under adhesive wear and abrasive wear.关键词
