Abstract
Application of hard coatings such as nitride, carbide, and nitrocarbide improves corrosion and wear resistance. In this work, an RF magnetron sputtering was used to coat TaC films with various target power values. Furthermore, TaCN films were deposited using nitrogen gas at the same target power values using the RF magnetron sputtering. Investigations were conducted on the mechanical, electrochemical, and tribological impacts of the carbide and carbonitride phases. TaN and TaC bonds were detected, and X-ray photoelectron spectroscopy (XPS) was used to analyze the chemical composition and bonding arrangement. TaCN films showed greater wear rate (2.06 × 10−7*mm3/Nm), corrosion resistance (44.811 × 10−6, mm·yr-1) in Ringer solution, and a lower friction coefficient (0.236) compared with TaC films.
期刊介绍：
The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
