Abstract In order to investigate the wear and protection on the rail surface of electromagnetic launch under extreme electromagnetic thermal coupling field, based on COMSOL and ABAQUS finite element software, the electromagnetic thermal model and the thermal-mechanical coupling wear model for Mo, Ni, W wear-resistant and conductive coatings were established, and the influences of different wear-resistant and conductive coatings on the electromagnetic thermal distribution of electromagnetic launch and wear resistance of the rail were explored. The results show that the coating surface alters the distribution of current density on the rails, reducing the thermal effects and lowering the overall temperature. During electromagnetic launching, mechanical wear on the rails is primarily concentrated on the front of the section, and the rail wear is significantly reduced after applying the coatings. For uncoated rails, the maximum wear depth is 1.142 μm, and the wear volume is 2.170 mm³; after applying the Mo, Ni, and W coatings, the maximum wear depths of the rail are 0.070, 0.095, and 0.042 μm respectively, and the wear volume ranges from 0.030 to 0.069 mm³. Among them, the W coating exhibits the lowest maximum wear depth and wear volume due to its superior thermal conductivity, excellent electrical conductivity, high hardness, and outstanding wear resistance.
