The interdiffusion between plated tin layer and copper zinc alloy substrate during heat treatment have been studied with special interest to the effect of the alloy composition on the diffusion behavior. Specimens were Cu-Zn alloys (5, 10, 20, 30 and 38 wt % Zn) plated with tin of 10μm in thickness. Heat treatments were made at 623, 673K for 1.8, 3.6 and 7.2ks. The diffusion layer formed was examined by optical microscope, EPMA and X-ray analysis, together with microhardness tester. Heat-treated specimens yielded η, ε or γ phases at the interface depending on temperature and alloy composition. The activation energies of γ phase formation in 5, 10 and 20wt % Zn alloys were 160, 130 and 91 KJ/mol respectively. The fact indicates that heat treatment at higher temperatures favors the formation of γ phase. The hardness of ε and γ phases were Hmv 400-420 and 480-500 respectively.
