Abstract
A number of experiments were conducted to measure the physical and mechanical properties of multielement coatings. To apply CrNiTiFeCu coatings on a nickel-chromium substrate, the technology of magnetron deposition in an atmosphere of argon or nitrogen was used. The results of measurements of the microhardness as well as the coefficients of friction and wear resistance of the applied CrNiTiFeCu thin films are presented. The findings indicate that the studied samples show a high microhardness and wear resistance. Consequently, there is a possibility to extend the lifespan of mechanisms and machines parts.
