Comparison of Ni-based SiC and B4C reinforcements on a TIG-coated AISI 1040 steel

Abstract In order to coat the surface of AISI 1040 steel using the TIG coating process, SiC and B4C are added to NiCrBAl powder at various rates. The microstructure and wear characteristics are then analyzed. Thus, it is intended to increase the AISI 1040 steel’s resistance to elements like abrasion and friction while lowering maintenance expenses. The ratio of B4C to SiC reinforcing powder affected the produced coating layer’s microstructure analyses and wear tests were carried out. Therefore, it has been found that the hard carbide phases and boron carbides generated in the coating layer have a favorable impact on wear, lowering weight losses and friction coefficients.
