Abstract
This study focuses on the application of a tetrahedral amorphous carbon (TaC Ti) nanocomposite coating on the selector carrier of a double diaphragm pump to reduce friction. The objective is to identify a suitable coating that can improve the lifespan of the carrier by introducing tribological properties. The research involves characterizing the coating's tribological properties, including the coefficient of friction (CoF) and wear resistance, through experimental testing and analysis. Furthermore, the mechanical properties of the coating, such as hardness and reduced modulus, are evaluated using nano-indentation techniques. At the end of this study, the coefficient of friction values for each coating were determined: uncoated (0.20), anodized coated (0.19), anodized with Teflon coated (0.16), and TaC-Ti (0.10). The results clearly indicate that TaC-Ti coating exhibits the lowest coefficient of friction among the tested coatings. This finding shows that TaC-Ti coating possesses superior tribological properties, making it a suitable choice or improving the lifespan of the carrier. By reducing friction and wear, the TaC-Ti coating can enhance the overall performance and durability of the carrier in practical applications. Additionally, the coating exhibits superior wear resistance and enhanced mechanical properties compared to other coatings. The findings from this study contribute valuable insights into the application of TaC-Ti nanocomposite coatings for friction reduction in double diaphragm pumps.
