| 摘 要： | 研究Ti-6Al-4V和Monel K500合金在海水和纯水环境下的腐蚀磨损性能,对偶材料为316不锈钢,实验装置为环-块摩擦磨损试验机。研究结果表明,Ti-6Al-4V和Monel K500合金在海水中的摩擦因数明显小于在纯水中的摩擦因数,在海水中的磨损量明显大于纯水中的磨损量,这主要是由于摩擦作用破坏了金属表面的钝化膜,增加了摩蚀速度。磨损和腐蚀产生交互作用,交互作用量随着腐蚀速度的加快而增加。当和Monel K500配副时,316不锈钢的磨损严重,而和Ti-6Al-4V配副时磨损相对较小。

| Abstract: | 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. |
