4. Conclusions
- (1)
- The microstructure and mechanical properties of γ-Fe2O3@SiO2-Ag nanocomposite coatings are influenced by the Ag content. There are holes in the nanocomposite coatings at the Ag content of 10 wt.% and 18 wt.%. The microstructure of the nanocomposite coatings is dense at the Ag content of 24 wt.%.
- (2)
- The CoF and wear rate of γ-Fe2O3@SiO2-Ag nanocomposite coatings decrease gradually with the increase in Ag content from RT to 300 °C.
- (3)
- At 500 °C, the lowest CoFs of 10 wt.%Ag, 18 wt.%Ag, and 24 wt.%Ag in the γ-Fe2O3@SiO2 nanocomposite coatings are 0.08, 0.05, and 0.06, respectively. At 600 °C, the CoFs of 10 wt.%Ag, 18 wt.%Ag, and 24 wt.%Ag in the γ-Fe2O3@SiO2 nanocomposite coatings decrease first and then increase, and the wear rate of the Ag-doped nanocomposite coatings is low compared with that of the nanocomposite coatings without Ag.
- (4)
- Ag plays a role in lubricating and reducing wear from RT to 300 °C. At 500 °C, γ-Fe2O3 in the γ-Fe2O3@SiO2 nanocomposite coatings becomes soft due to the friction heat and the environment temperature and is easy to shear and lubricate with Ag. The CoF of the nanocomposite coatings is as low as 0.1. At 600 °C, the tribological properties of the nanocomposite coatings become worse due to the oxidation of Ag and the phase transition of γ-Fe2O3 in the nanocomposite coatings.
