【摘要】 对０Ｃｒ＿（１３）Ｎｉ＿５Ｍｏ，０Ｃｒ＿（１６）Ｎｉ＿５Ｍｏ和２０ＳｉＭｎ、三种材料不同的热处理方法，在转盘试验机上进行了含沙量高达６０ｋｇ／ｍ￣３的５种不同含沙量下磨损与磨蚀的试验研究。得到了０Ｃｒ＿（１３）Ｎｉ＿５Ｍｏ采用１０３０℃淬火，４７０℃一次回火的较佳工艺。更多还原

【Abstract】 Three metallic materials0Cr₁₃Ni₅Mo,4Cr₁₆Ni₅Mo and 20SiMn processed withdifferent heat treatments are tested and investigated on the disc wearing rig in silt laden wa-ter with 5 kinds of sand contents up to 60 kg/m￣3. The results show that the chilled 0Cr₁₃Ni₅Mo steel, quenched at 1030℃ and tempered at 470℃, is superior to others in wear andwear-cavitation properties.更多还原
