Comparative analysis of electrolytic plasma nitriding and ion nitriding of R6M5 high-speed steel

Abstract

The article examines the influence of surface hardening methods - electrolytic plasma nitriding (EPA) and ion nitriding (IA) on the properties and structure of samples made of high-speed tool steel P6M5 with preliminary plastic deformation by asymmetric rolling.. The processing time, the depth of the nitrided layer and the surface microhardness were compared. Experimental methodology: conducting electrochemical oxidation in an electrolyte based on ammonium chloride and ammonia (10% NH₄Cl + 5% NH₃) and conducting ionizing radiation in a glow discharge. The study included measuring Vickers microhardness.The study methods included EPN in an electrolyte based on ammonium chloride and ammonia (10% NH₄Cl + 5% NH₃) and ion nitriding in a glow discharge; and Vickers microhardness measurements.
