摘　　要：以CuSO4中Cu2+离子模拟铜矿浆料,研究了低铬白口铸铁在含Cu2+离子的浆料介质中的腐蚀磨损特性。结果表明,低铬白口铸铁在Cu2+离子的浆料介质中的磨损机制以显微切削、犁沟和腐蚀剥落为主;通过控制铸铁中的含碳量、加入微量镍,可以提高铸铁的韧性,同时向矿浆中加入石灰石(CaO)等措施,可以提高其抗腐蚀磨损能力。With Cu2＋ in the CuSO4 modeling slurries of copper mine, the corrosive-wear resistance of low chromium white cast iron was studied. The results show that the corrosive-wear mechanism of low chromium white cast iron in slurries with Cu2＋ is dominated by micro-cutting, groove and corrosion spalling; the corrosive-wearing resistance can be improved by controlling the carbon content, adding nickel to the iron and adding CaO to the slurries.
