the main aim of this research was to investigate the effects of plasma nitriding parameters including frequency and duty cycle for a seris of test samples with different grooves during conventional plasma nitriding (cpn) and active screen plasma nitriding (aspn) treatments. the sample assemblies were consisted of rectangular grooved steel blocks with different groove dimensions of 2, 4, 6, 8 an...

Original scientific paper In this paper, the results of investigations of the temperature field distribution and tool wearing during C60 steel turning are presented. Abrasive wear resistance tests were carried out for cutters made of low-alloy high-speed steel. Steel samples were heat treated, and then were subjected to ion nitriding, TiN coating, or to complex treatment. The influence of cutti...

in the present work the effects of plasma nitridization on the passivation behavior of aisi 316l was investigated. to do this; nitriding treatments were carried out at 420°c for 1, 2, 4 and 16 hours. the phase composition and structure of the nitrided layer were studied by low angle x-ray diffraction and scanning electron microscopy. the hardness of samples also was evaluated by vickers microha...
