Sliding wear of low carbon steel modified by double-glow plasma surface alloying with nickel and chromium at various temperatures

This paper was directed at improving the wear resistance of low carbon steel by double-glow plasma surface alloying (DPSA) technology. A Ni–Cr alloyed layer was successfully formed on the low carbon steel by the DPSA treatments. The microstructure, elements distribution, phase identification and micro-hardness were analyzed by SEM/EDS, XRD and nano-indentation. Detailed tribological characterization was carried out by using a ball-on-disc...
