Carbides reinforced intermetallic matrix composite coatings for elevated temperature environmental resistance were prepared on Ni-based suaperalloy substrate using CO2 laser cladding process. The phases of clad layer were investigated by scanning electron microscopy (SEM), X-ray diffractometer (XRD) and energy-dispersive spectrometer (EDS). The laser cladding of the Ni78Si13Ti9/WC powder shows that the products mainly consist of TiC, WC and Ni3(Si,Ti) phases. A chemical reaction between WC particle and Ti powder occurs during the laser process, therefore TiC is formed. The microhardness of the samples increases with the increase of the content of WC.
