Electron microscopy analysis of the “plasma coating – substrate” contact zone

Using modern physical materials science methods, the structural-phase states and elemental composition of the transition zone in the “plasma coating (high-speed molybdenum steel) – substrate (medium-carbon steel)” system were investigated. It was found that the transition layer, approximately 100 micrometers thick, contains $\alpha$-phase, $\gamma$-phase, complex carbides ($M_{23}$С$_6$, $M_6$С), as well as MoC and cementite.
