Abstract

Abstract. In this paper by X-ray phase analysis and electron microscopic method studied fine structure, morphology and phase composition of samples of R6M5 steel before and after electrolytic-plasma nitriding. It is shown that the microstructure of the R6M5 steel in the initial state, i.e. after normal heat processing consists of tempered martensite and carbides solid M6C and MC-type with spherical shape. Revealed that the martensite structure after nitriding more fragmented. Found that after electrolytic-plasma nitriding at 550°C for 7 minutes in the surface layers of R6M5 steel CrN fine nitrides are formed. Microdiffraction method electrons is determined that the structure after nitriding steel R6M5 nitrogen martensite comprises carbides (M6C and MC), Fe4N nitride and CrN fine nitride.

Keywords: structure, phase composition, nitriding, high-speed steel, carbide.
