Abstract
- Different amounts of PTFE were doped in the process of Cr3+ electroplating to form Cr3+ composite coating. The effects of PTFE particles with different concentrations on the micro-structure and mechanical properties of Cr3+ composite coating were studied in this paper. The micro-structure and mechanical properties of Cr3+ coating were characterized and tested by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), nano-indenter and friction wear testing machine, respectively. The results show that different concentrations of PTFE had significant effects on the micro-structures and mechanical properties of Cr3+ composite coatings. When the concentration of PTFE in the plating solution was 12.5 mL/L, the current density was 35 A/dm², the pH was about 2.0, the temperature was 45 °C, and the deposition time was 20 min, the obtained Cr3+ composite coating had the best comprehensive performance, with the hardness of 6.8 GPa and the lowest friction coefficient value of 0.28.
