Plasma Surface Treatment of CoCr and NiCr Alloys for Dental Applications: A Comparative Study of TiN Thin‐Film Plasma Deposition Techniques
Cobalt–chromium (CoCr) and nickel–chromium (NiCr) alloys have been widely employed in dentistry as biomaterials, owing to their exceptional physical and mechanical properties, coupled with excellent biocompatibility and low cost. In this study, it is aimed to conduct a comparative analysis of titanium nitride (TiN) thin films synthesized via cathodic cage TiN deposition and hollow cathode (HC) TiN deposition techniques. Thin films are deposited onto CoCr and NiCr alloy substrates. The fabricated thin films are characterized using X‐ray diffraction, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, atomic force microscopy, Vickers microhardness tests, and abrasive microwear tests. It is observed that the TiN films deposited on the alloys exhibit promising performance, resulting in a 94% increase in wear resistance across the samples. Additionally, an enhancement in microhardness is noted, particularly for the samples treated by HC deposition, which demonstrates superior wear resistance, a critical property for dental applications.
