In order to choose the material of high-pressure pump in seawater desalination, the friction pair of TC4 titanium alloy and 2205 duplex stainless steel was studied in detail. Friction and wear tests were carried out under dry friction, pure water, and seawater media. The friction coefficient and wear extent of friction pair were obtained quantitatively, and the surface topography of friction samples was analyzed. The results showed that the abrasion of 2205 stainless steel and TC4 titanium alloy in seawater was less than in pure water and air/dry friction due to the lubrication effect of seawater medium. The abrasion resistance of 2205 stainless steel was better than that of TC4 titanium alloy. Compared with the rotating speed, the load has little effect on the friction coefficient.
