Chibane, H. Ait-Amokhtar and C. Fressengeas, On Mechanical and Wear Properties of 42CrMo Steel by Plasma In this work, a new structure consisting of a hollow cathode metal plate can produce a hollow cathode discharge and heat the workpiece by radiation. This principle is used to perform hollow cathode source plasma nitriding (HCSPN). Herein, 42CrMo steels were treated by conventional plasma nitriding (CPN) and HCSPN treatments.

The microstructural charaterization and phase analysis of resultant nitride layers were performed using optical, scanning electron microscopy, electron probe microanalyzer, X-ray diffraction methods and hardness measurements.

The effect of novel composite pretreatment on performances

Abstract Novel composite pretreatment combining laser shock peening and pre-oxidation was primarily adopted prior to plasma nitriding for 42CrMo steel. Optical microscope, scanning electron microscope, vickers microhardness tester and wear tester were used to systematically investigate the innovative enhancement effect of novel composite pretreatment on the performances of plasma nitrided layer.
