The deposition of Ti--Si--C thin films by magnetron sputtering was examined at low preparation temperatures using elemental targets of titanium, silicon, and carbon to investigate the effects of substrate temperature on the formation of carbide compounds, such as TiC<inf>x</inf>and/or Ti<inf>3</inf>SiC<inf>2</inf>, and thereby on mechanical properties, such as hardness, and on physical properties, such as the electrical conductivity, of thin films. It was found that Ti--Si--C thin films with an excellent electrical conductivity of approximately 200 μ\Omega cm and a surface hardness larger than 10 GPa could be deposited at a temperature of 500 °C, which is much lower than conventional deposition temperatures, such as 800 °C. Thus, it is expected that this deposition process will be more useful for providing protective coatings for electrical friction contacts. Furthermore, the highest corrosion protection performance was observed in the stainless steel coated with the Ti--Si--C films at 500 °C. Therefore, it is also expected that the corrosion protective property of stainless steel substrates will be improved by coating with the thin films at a temperature of 500 °C, which is much lower than conventional deposition temperatures, such as 800 °C.
