摘要: 利用OM和SEM对0%Sb和0.2%Sb的两种马氏体钢的微观组织与腐蚀产物进行表征,测量其硬度和力学性能,并进行腐蚀磨损试验,研究了Sb元素的加入对试验钢耐磨蚀性能的影响。结果表明:试验钢具有高抗拉强度、高硬度及良好的低温(-20 ℃)冲击性能,分别能够达到1400 MPa、40 HRC以及45 J以上,0.2%Sb钢的耐磨蚀性更好。Sb元素的加入提高了钢在酸性高氯离子及高硫酸根离子环境中的耐蚀性,保证力学性能与硬度的同时提高了耐磨蚀性能。

Abstract: Two martensitic steels containing 0%Sb and 0.2% Sb were analyzed to research the influence of the addition of Sb on the wear resistance under corrosive environment. The microstructure and corrosion products were characterized by OM and SEM. Then the hardness, mechanical properties and corrosive wear properties were tested. The results show that the tested steels have high tensile strength, high hardness and good impact performance at low temperature (-20 ℃), which can be over 1400 MPa, 40 HRC and 45 J respectively, while the steel containing 0.2%Sb has better corrosive wear resistance. The Sb addition improves the corrosion resistance of the steel in acidic high chloride ion and high sulfate ion environment, improving abrasion resistance as mechanical properties and hardness ensured.

Key words: Sb-containing steel, corrosion resistance, corrosion mass loss, corrosive wear
