Plasma nitriding is a plasma-activated thermochemical method widely used to increase the fatigue strength, hardness and wear resistance of low-alloy steels. In this work, new structure consisting hollow cathode metal plate can produce discharge heat workpiece by radiation. This principle perform source plasma (HCSPN). Herein, 42CrMo steels were treated conventional (CPN) HCSPN treatments. The n...

The aluminum-L,,VV Auger spectra for elemental Al. Al oxide and Al nitride have been measured in an assessment of the utility of Auger spectroscopy in characterizing thin oxidized Al films used in model supported-metal catalyst studies. Clearly distinct spectra were found for the three surface chemical states. The oxide spectrum was shown to be similar to published spectra from bulk, single-cry...

The nickel–iron–chromium (alloy 20) is enriching by hybrid surface treatment through plasma nitride (PN) and physical vapor deposition (PVD) process. nitriding process takes 12 h at 500 °C. Potentiodynamic testing used to characterize the corrosion performance of treated material, followed morphological analysis exposed surface; XRD, EDX, SEM, hardness, tensile are investigate appropriate coati...

This work concerns two stages of research into plasma nitriding (change steel and modification parameters). In the first stage, pins obtained from currently used were compared with made an alternative material available on market, using same process parameters. As a result metallographic tests carried out, in case, presence thin, porous, heterogeneous nitrided layer or its absence was found, co...

In this work, TiN/TiCN & PN/TiCN multilayer films were deposited by plasma- assisted chemical vapour deposition (PACVD). Plasma nitriding (PN) and TiN intermediate layer prior to coating leads to appropriate hardness gradient and it can greatly improve the mechanical properties of the coating. The composition, crystalline structure and phase of the films were investigated by X-ray d...
