Outline
The friction pairs， such as the valve core and valves of seawater pumps， are under the conditions of seawater corrosion and wear （referred to as “tribocorrosion”）. The tribocorrosion resistance of materials directly affects the service life and safety reliability of marine engineering equipment. In-situ corrosion friction tests are adopted to quantitatively study the corrosion and wear mechanisms of three passivable alloys： titanium alloy （Ti75）， stainless steel （316SS）， and aluminum alloy （5083） in a 3.5%（mass fraction） NaCl aqueous solution. The results show that due to the lubricating effect of the erosion products of Ti75， corrosion and wear have a negative synergy， reducing the amount of wear， while the corrosion and friction of 5083 aluminum alloy and 316SS samples promote each other. The corrosion rate and tribocorrosion rate（2.25×10-3 mm3/（N·m）） of 5083 aluminum alloy are both the highest， while the tribocorrosion rate of 316 stainless steel （6.78×10-6 mm3/（N·m）） is the lowest. Among the three materials compared in this article， 316SS is the best material for manufacturing wear-resistant parts in seawater.
