WC/Ni Bronze Composite Material Formation by Combined Methods ofLaser Cladding and Cold Spraying.

Formation of composite material containing anti-friction bronze CuA18.5Fe4Ni5Mnl.5 and reinforced by inner bulk profiled frame of WC/Ni was considered. Combined methods of laser cladding and cold spraying were used. Reinforced cold spraying copper-bronze blend deposits on profiled frames of WC/Ni produced by laser cladding were obtained. Dependence of bronze weight concentration in cold spraying copper-bronze deposit on bronze weight part in powder blend was analyzed. Results of non-contact profiling of reinforcing WC/Ni frame, EDS analysis and microhardness tests of obtained reinforced copper-bronze-WC/Ni composites were presented. [ABSTRACT FROM AUTHOR]
