摘　　要：研究了３８ＣｒＭｏＡｌ钢调质与离子渗氮试样在海水和砂粒（尺寸１００～１０００μｍ）以不同速度（１４，２４，３６，５和７ｍ／ｓ）冲击作用的腐蚀冲刷磨损行为。研究结果表明，调质试样的平均磨损速率随冲刷速度的增加发生明显变化，腐蚀冲刷磨损严重；离子渗氮试样的平均磨损速率随冲刷速度变化很小，腐蚀冲刷磨损轻微。It has been studied that 38CrMoAl steel specimens which are treated in refining and (or) in plasma nitriding.The behaviour of erosion\|corrosion wear in sea\|water containing the sand (size of 1001000m) at different impact speed (1.4,2.4,3.6,5 and 7m/s) is exhibited.The results show that the erosion\|corrosion wear mass loss is severe for refined specimens and very slight for plasma\|nitrided ones;the average wear rate obviously increases with the impact speed for refined specimens and slightly increases with the impact speed for plasma\|nitrided ones.It exhibits that the plasma\|nitrided specimen surface has hard nitride and excellent resistances to erosion\|corrosion wear.
