摘要(Abstract):
研究TC4钛合金、Hastelloy C-276合金、Inconel 625合金和Monel K500合金与316不锈钢对磨时在纯水和模拟海水下的摩擦磨损行为,评价海水腐蚀环境对几种耐海水腐蚀材料耐磨性的影响以及316不锈钢与几种金属配副的磨损行为。结果表明,四对摩擦配副在纯水润滑条件下的摩擦系数明显大于其在海水润滑条件下的摩擦系数,海水具有较好的润滑作用。在腐蚀磨损过程中,腐蚀磨损交互作用量占总腐蚀磨损量的比例ΔV/V为45%~86%,表明在海水环境下腐蚀与磨损的交互作用不可忽视。与不同金属对磨时,316不锈钢对偶材料的磨损量表现出不同的趋势,这可能与摩擦过程中存在的电偶腐蚀有关。
