Abstract: The geometrical profiles, dilution, WC distribution, microstructure and dry sliding wear resistance of Ni60A+35% WC coatings by individual laser cladding and laser-induction hybrid cladding are analyzed and compared. The results show that the maximum laser scanning speed and the maximum rate of powder feeding are only 600 mm• min–1 and 25 g•min–1, respectively. If the same processing parameters are adopted during laser-induction hybrid cladding, the width, the heat-affected-zone and the dilution of coating are larger than those of coating by individual laser cladding, but the height of coating is lower than that of coating by individual laser cladding and the dry sliding wear resistance of coating is worse than that of coating by individual laser cladding. However, the maximum laser scanning speed increases to 2 200 mm•min–1 and the maximum rate of powder feeding increases to 75.6 g•min–1 during laser-induction hybrid cladding, whose processing efficiency is much three times higher than that of individual laser cladding. WC particles distribute homogeneously and no cracks are detected in the coating with a dilution of less than 5.2%, whose dry sliding wear resistance is approximately 1.42 times higher than that of coating by individual laser cladding
