英文摘要	To investigate the microstructure characteristics of a multiphase composite coating of Ni-based/Cu-based alloys, we prepared multivariate multiphase composite coatings of Ni60/high-aluminum bronze by supersonic plasma spraying technology on a #45 steel substrate, in which the content of high-aluminum bronze is 30%. We then analyzed the organizational structure, element distribution, phase composition, and micro-defects of the composite coatings. The results show that the microstructure of the composite coating of two kinds of alloys was distributed as a stacked layer arrangement, the organization structure had the characteristics of a gradient composite coating, the coating structure was compact, and the micro-interface integration was favorable. The elements of two types of alloys of high-aluminum bronze alloy and Ni60 were distributed in a staggered form, and mutual diffusion occurred. The high-aluminum bronze alloy cladded the Ni60 alloy particles and filled the micro-interface of the organizational structure. At the same time, a metallurgical reaction took place between the two kinds of alloys. As a result, the micro-interface bond was stable. Compared with the coating of pure Ni60 alloy, the addition of high-aluminum bronze can effectively reduce the coating defects and thus decrease the size of the defects of multivariate multiphase composite coatings. © 2016, Editorial Board of Journal of Harbin Engineering.
