“…As shown in Figure 13 , as the ion gas flow rate increases, the tensile strength first decreases and then increases. When the ion gas flow rate was 1.5 L/min, the maximum sample strength was 811 MPa, which may be because the ion gas flow rate at this point matched the protective gas flow rate and the arc current, allowing the arc to reach stability [ 29 ]. As the ion gas flow rate increases, the arc stiffness increases, the molten pool temperature formed during plasma surfacing is higher, and the carbide content in the coating increases (as shown in Figure 6 ), resulting in a decrease in tensile strength.…”

In this study, we developed composite Fe-Cr-V-C coatings by plasma transferred-arc (PTA) powder surfacing on a 42CrMo steel substrate. The effects of arc current and ion gas flow rate on the coatings’ microstructure, hardness, and bonding performance were investigated. During the surfacing process, VxCy,M7C3M=Fe,Cr and other hard phases are in-situ generated throughout the entire PTA powder surfacing. These phases are uniformly distributed in the Fe matrix through precipitation and dispersion strengthening, yielding a surface hardness of up to 64.1 HRC. Also, the bonding performance between the substrate and coatings was evaluated by measuring the tensile strength, revealing that strong metallurgical bonds are formed, reaching a strength greater than 811 MPa.
