Fe60 + WC composite coating with different quality fraction was prepared on the surface of Q235 carbon steel, and the macromorphology of microscopy, microhardness tester, scanning electron microscopy (SEM), energy spectroscopy analyzer (EDS), and X-ray diffractometer (XRD) were studied. The results show that WC addition can form a hard phase, so that the added Fe60 coated coating can effectively improve the hardness of Q235 carbon steel. When the WC mass fraction is 3%, the hardness is 8 times of the substrate, which reaches the maximum.
