利用环块摩擦磨损试验机研究了Ti-6Al-4V和Monel K500合金与316不锈钢在人工海水和蒸馏水中的摩擦磨损行为。研究发现，与海水相比，蒸馏水中的摩擦系数一般较大。与蒸馏水相比，Ti-6Al-4V和Monel K500合金在海水中的磨损量较大。机械作用会破坏钝化膜，增加腐蚀速率。腐蚀与磨损之间存在协同效应。腐蚀与磨损之间的协同作用与腐蚀速率有关，且随着腐蚀速率的增加，协同作用变得更加重要。在蒸馏水和海水中，316不锈钢与Monel K500合金的摩擦磨损比与Ti-6Al-4V合金的滑动磨损严重。
The tribocorrosion behaviors of Ti-6Al-4V and Monel K500 alloys sliding against 316 stainless steel were investigated using a ring-on-block test rig in both artificial seawater and distilled water. It is found that friction coefficients are in general larger in distilled water compared with seawater. The wear losses of Ti-6Al-4V and Monel K500 alloys are larger in seawater compared with distilled water. The mechanical action can destroy the passive film and increase the corrosion rate. The synergism effect between corrosion and wear occurs. The synergism action between corrosion and wear is related to the corrosion rate and with the increase of corrosion rate, the synergism becomes more important. 316 stainless steel suffers severe wear sliding against Monel K500 alloy compared with sliding against Ti-6Al-4V alloy in both distilled water and seawater.
