Effect of Pulsed Plasma Nitriding on Mechanical and Tribological Performance of Ck45 Steel

 We studied the mechanical properties and wear performance of AISI 1045 (Ck45) carbon steel under the influence of pulsed plasma nitriding. The treatments were performed at temperatures of 500 and 550 C in N2:H2 gas ratios of 1:3 and 3:1 and the working pressure of 10 mbar for 1 to 4 hours. Samples were examined

Tribological performance of plasma nitrided gamma based titanium aluminides

Ti–48Al–2Nb–2Mn (at.%) alloy was plasma nitrided to investigate the effect of this thermochemical surface modification on the tribological behavior of gamma based titanium aluminides. The effects of nitriding temperature, nitriding time and H2/N2 gas ratio were investigated. Characterization of the microstructure and phases formed within the nitrided surface layers was performed using optical and electron
