Comparative study on the tribological performances of FeCoCrNiB <sub>0.15</sub> /diamond composite against SiC and ZrO <sub>2</sub> ceramics
Abstract In present study, the friction behaviors of high‐entropy alloy (HEA)‐based diamond composites against ZrO 2 and SiC ceramic ball were studied to provide insights into the grinding mechanism and tribological properties of the HEA/diamond composite as a function of friction ball material. The coefficients of friction (COFs), wear rate, material removal mode, and tribological mechanism of HEA/diamond composites against ZrO 2 and SiC ceramic balls were investigated. The results show that the COF and wear rate against SiC ball are significantly higher than those obtained under the ZrO 2 ball. The main wear mechanism of the HEA/diamond composite against the SiC ceramic ball is adhesion wear, whereas against the ZrO 2 ceramic ball, the wear mechanism is dominated by abrasive wear. On the other hand, the material removal mode is ductile deformation for ZrO 2 and brittle fracture for SiC. Microstructural observation shows that a metallic film is formed between HEA/diamond composite and the ZrO 2 ball, which is transferred to the surface of ZrO 2 and can, thus, reduce the direct contact between ZrO 2 and HEA/diamond composites.
