| Abstract: | Several nikel-base WC composite alloy with various Ceo2 content were remelted by means of a 5 kWcontinuous wave CO2 laser on the substrate of steel 40Cr. The effect of WC and CeO2 content on the microstruture andcorrosion resistance of laser remelted c0atings was studied. As a result,adding proper content of WC and CeO2 in thealloy powder and laser remelting can not only modify the microstructure but also improve the corrosion resistance ofthe coatings remarkably. |
