In order to improve the hardness and wear resistance of Q235 steel, Ni-Ti-Cr-(CNTs) composite coatings was prepared on the surface of Q235 steel by laser cladding technology, and the effects of laser cladding parameters on the forming quality, microstructure and mechanical properties of the composite coatings were studied. Results indicate that the principal phases of the composite coatings consist of TiC, Fe2Ti, Cr7C3, FeNi, (Fe,Ni), and Cr, with the laser cladding parameters exhibiting minimal impact on the primary phase compositions of the coatings. With lower laser specific energy, a poor bond between the coating edge and substrate is observed. However, as the laser specific energy increases, reinforced ceramic particles within the composite coating enlarge, and an escalated level of iron seeps into the composite coating from the substrate, consequently reducing its hardness and wear resistance. Compared with Q235 low carbon steel substrate, the maximum microhardness of the composite coatings is approximately 5 times greater and demonstrates significant improvements in wear resistance.
