“…45 steel produces a large amount of scrap due to its low surface hardness and poor wear resistance [1][2][3]. Scanning electron beam can effectively change the surface microstructure and improve surface performance, due to its "uniform energy density distribution, sudden heating and rapid cooling" characteristics [3,4]. By adding different alloy elements, the alloy layer can form a special phase structure and improve the corresponding surface performance, and improve the disadvantages such as weak adhesion and loose organization [5], SEBSA is used to treat the surface of 45 steel, effectively improving its utilization rate.…”

In order to improve the surface properties of 45 steel, the effects of different scanning electron beam treatments on the surface properties of 45 steel were studied. The research results indicate that after scanning electron beam surface alloying (SEBSA) treatment, in addition to forming needle like martensite, carbides (tungsten carbide and molybdenum carbide) also exist in the alloying zone of the strengthening layer, moreover, the grains become finer. After scanning electron beam alloying treatment, the surface hardness reached 1250HV, which is 5-6 times the substrate. Compared with the wear loss of the matrix, the wear resistance of the sample after SEBSA treatment increased by nearly six times.
