Abstract: After brass is coated with tin, heat treatment makes the coating metal Sn and the substrate metallic elements Cu and Zn diffuse with each other. This causes the coating composition to be changed and the interface to be strengthened. The diffusion coating with a multiphase structure formed by this process has excellent properties of antifriction and wear resistance. With the aid of scanning electron microscopy, electronic probe microanalysis and X-ray diffraction, the mechanism of the propert, ies is discussed.
Key words: brass; tin coating diffusion; antifriction and wear resistance; multiphase structure
