“…Therefore, the heating efficiency in HCD plasma nitriding can be raised compared to conventional plasma nitriding. This results in an effective treatment of austenitic stainless steels, promoting a uniform single S-phase layer without the CrN precipitation, enhanced hardness, and wear and corrosion resistance [31][32][33][34][39][40][41][42].…”

Low-temperature plasma nitriding is a thermochemical surface treatment that promotes surface hardening and wear resistance enhancement without compromising the corrosion resistance of sintered austenitic stainless steels. Hollow cathode radiofrequency (RF) plasma nitriding was conducted to evaluate the influence of the working pressure and nitriding time on the microstructure and thickness of the nitrided layers. A group of samples of sintered 316L austenitic stainless steel were plasma-nitrided at 400 °C for 4 h, varying the working pressure from 160 to 25 Pa, and the other group was treated at the same temperature, varying the nitriding time (2 h and 4 h) while keeping the pressure at 25 Pa. A higher pressure resulted in a thinner, non-homogeneous nitrided layer with an edge effect. Regardless of the nitriding duration, the lowest pressure (25 Pa) promoted the formation of a homogenously nitrided layer composed of nitrogen-expanded austenite that was free of iron or chromium nitride and harder and more scratching-wear-resistant than the soft steel substrate.

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.

Cutting tools made of high-speed steel have significant economic and technological importance. To enhance their productivity, thermochemical treatments are sought to improve both surface mechanical and tribological properties. Plasma nitriding and thin film deposition are widely employed for this purpose. In this study, modifications were made to M2 high-speed steel drills through plasma nitriding at temperatures of 400°C and 450°C. Cathodic cage TiN plasma deposition was also performed, varying the dwell time at a fixed temperature of 450°C. Characterization techniques included optical microscopy, X-ray diffraction (XRD), Vickers microhardness testing, and scanning electron microscopy (SEM). Performance tests were carried out to evaluate the behavior of the drills in relation to wear when machining AISI 1020 steel. It was observed that longer deposition times promote more uniform and thicker layers, and higher nitriding temperatures result in thicker nitride layers. An increase in hardness was noticeable in all deposition and nitriding treatments, with the nitrided samples exhibiting the highest hardness. During performance tests, the cathodic cage plasma TiN deposition demonstrated greater potential for application in HSS drills, with a treatment lasting 4 h providing the best results.
