**4. Conclusions**

By ion-beam-assisted bombardment technology, the GH4169 alloy implanted with Ag, Mo, and Ag–Mo, respectively, were prepared at RT. The microstructure, phase compositions, tribological behavior and mechanism were investigated. The conclusions drawn are as follows:


• During the preparation process and sliding at RT, the formation of silver molybdate can be achieved through ion-beam-assisted bombardment, an unbalanced preparation method.
