Abstract

The structural and phase states, as well as the elemental composition of the transition zone in the "plasma coating (molybdenum high-speed steel) – substrate (medium carbon steel)" system, have been investigated. It has been established that the transition layer, approximately 100 μm thick, contains an α-phase, γ-phase, complex carbide phases (Me23C6, Me6C), as well as MoC and cementite. No microcracks or microdiscontinuities were detected in the transition layer.
