25/7/2006· The phase constituents of Cu, Cu2 O, CuO, Cu 3Si, Si, and SiC in the plasma-sprayed deposits were analyzed by XRD. The SiC was decomposed into Si and C, and copper silicide was then formed. Most pores were found in the vicinity of SiC due to the decomposition of the SiC and thermal expansion mismatch between SiC and Cu during rapid solidifiion.
