腐蚀磨损过程中材料的环境脆性

从腐蚀磨损的交互作用、腐蚀磨损与应力腐蚀及氢脆的异同出发，论述了磨损加速腐蚀及腐蚀加速磨损的微观机制，指出材料的环境脆性与腐蚀对磨损的加速作用程度有关．从腐蚀对磨损的加速作用、比能耗、磨痕硬度等方面分析了不锈钢 Cl^-体系、Ni-P镀层 NaOH溶液、H4340钢与Ti6A14V合金 稀硫酸溶液体系、铜合金 NH4^ (NH3)或S^2-溶液中的环境脆化行为和规律，总结出材料环境脆性的力学判据，展望了今后腐蚀磨损的研究方向．

Environmental embrittlement of materials in corrosive wear

The synergistic mechanism between corrosion and wear was discussed from the aspects of wear-induced corrosion and corrosion-induced wear in this review. The environmental embrittlement of materials was defined by the amount of corrosion-induced wear in the corrosive wear. The corrosive wear behavior of stainless steel-CI- system, Ni-P-NaOH system, H4340 steel and Ti6AI4V-dilute sulfuric acid system and copper alloys-NH4+ (NH3) or S2- systems was analyzed from corrosion-induced wear, specific impact energy consumption and microhardness of worn surface, and the mechanical criterion of corrosive wear was set up. Finally the further investigations were suggested based on our research works in recent years.
