The NiAl-SiC composite coatings with different SiC contents are prepared on the surfaces of 1Cr17Ni2 steels by the laser cladding technique, and the phases, microstructures, chemical compositions and friction properties of the cladding layers are investigated. The results show that the cladding layers mainly contain AlFe0.23Ni0.77 and AlNi phases. The NiAl-SiC composite coatings have some defects, such as micro cracks, voids and falling off. The average friction coefficients of the cladding layer with a SiC mass fraction of 3% and the substrate are 0.731 and 1.260, respectively, indicating that the wear resistance property of the cladding layer is superior to that of the substrate.
