| Abstract | Passive alloys require not only high resistance to corrosion but also excellent tribological properties for seawater equip- ment applications. In this research, the tribocorrosion behav- iors of Inconel 625 alloy sliding against 316 stainless steel were investigated using a ring-on-block test rig in artificial seawater and distilled water. The results showed that the friction coeffi- cients were larger for sliding in distilled water as compared to seawater. However, the wear loss of Inconel 625 and 316 steel alloys was lower for sliding in distilled water than that in sea- water. Interestingly, the corrosion of seawater obviously accel- erated the wear. Moreover, with the increase of normal load, the wear loss increased but the average friction coefficient de- creased in both aqueous media. The synergistic effect between wear and corrosion was significant, due to the mechanical re- moval of passive film. Seawater salinity does significantly in- fluence the friction coefficient and wear loss. The Inconel 625 alloy has a maximum corrosion rate in 3% seawater, which is due to the synergism of salt concentration and dissolved oxy- gen in seawater. The high corrosion rate accelerated the wear loss but decreased the friction coefficients. |
