The flexible metallic cloth was made of mixed powder consisting of WC and organic blend. A brazing coating was obtained through the high temperature brazing of the metallic cloth in vacuum furnace. The anti-corrosion of the brazing coating was investigated by weight-loss method and electrochemical measurements. The surface morphology observation was conducted by the scanning electron microscopy (SEM). The results show that the composite coating has superior corrosion resistance compared with 316L stainless steel.
