Abstract: In order to improve the high temperature wear-corrosion resistance of 316L submerged roll of aluminum plated zinc plate production unit, Fe60 coating and four kinds of Fe60 composite coatings containing Mo(mass fraction 2.5%, 5.0%, 7.5%, 10.0%) were prepared on the surface of 316L matrix by laser cladding technology. The phase, microstructure, mechanical properties, frictional properties and corrosion properties of different coatings were characterized to explore the effect of Mo content on the microstructure and properties of Fe60 coatings. The results show that the hard phase Fe_9.7Mo_0.3 is precipitated with Mo coating. Mo has an effect on the grain size and microstructure defects of Fe60 coating, with the increase of Mo content, the grain size and microstructure defects of Fe60 coating decrease first and then increase, and w(Mo)=5.0% has the smallest grain size and no microstructure defects. Compared with Fe60, the hardness of the coating containing Mo decreases, while the wear resistance of the coating increases. With the increase of Mo content, the wear resistance of the coating increases first and then decreases, and w(Mo)=5.0% has the lowest wear loss. Compared with Fe60 coating, the corrosion resistance of the coating containing Mo is improved, with the increase of Mo content, the corrosion rate of the coating decreases, but when the Mo mass fraction exceeds 5%, the corrosion resistance of the coating decreases.
