The aim of the present study was to develop the hybrid method which allows producing highly corrosion-resistant composite titanium nitride layers on the AZ91D magnesium alloy. The hybrid method combines the deposition of composite titanium nitride layers using the PVD methods with the final tightening of the layers by a simple chemical-type treatment. The tightened multilayer obtained by the hybrid...
Beside its conventional applications such as improving the wear resistance of machine parts and tools, plasma thermochemical treatment (PTT) can be successfully used as a method for surface modification to achieve specific surface properties. Surface electrical conductivity of austenitic stainless steel sheets, for example, can be significantly enhanced by means of plasma nitriding. Such materials...
Good oxidation and corrosion resistance are required for cutting tools and other industrial components used in high temperature applications. The highest operational temperature of CrN is normally about 500 °C. A denser Cr–N coating prepared by high power pulsed magnetron sputtering – plasma immersion ion implantation & deposition shows oxidation resistance up to 800 °C compare with those prepared...
The present work is devoted to the short-time plasma nitriding of EN 1.4301 (AISI 304) austenitic stainless steel sheets in a pulsed glow discharge by means of a novel strip hollow cathode process for plasma thermochemical treatment (SHC-PTT) aiming at their use as bipolar plates of proton exchange membrane fuel cells (PEMFC). The fundamental trends in the change of the interfacial contact resistance...
