Experimental Study of the Nitriding Layer by Steel 17CrMoV10 (original) (raw)

Abstract

The aim of this research, is the experimental study of the nitriding layer during the process of nitriding in gases in Steel 17CrMoV10. It is well known that the process of nitriding is a thermal-chemical process that occurs at temperatures 500-600°C, where the enrichment of the peripheral surface with nitrogen is achieved. This surface is also, called a nitriding layer or diffusions layer. The aim of the process of gas-nitriding is the improvement of the properties of the material, such as, increase of the mechanical hardness and corrosion resistance, increase of resistance under thermal activities and resistance against consumption, etc. Final results of the process depend on the parameters that define the process: Temperature, duration of the process, concentration of the alloy elements in steel, etc. Depending on these parameters, by experimental methods-metallographic, microhardness measurements and microsond-we have studied the diffusions layer.
