本文设计了用于含有磨粒的强酸介质的新型耐磨蚀钢的化学成分，采用金相显微镜、Ｘ射线衍射、扫描电子显微镜、腐蚀与磨蚀试验等方法，观察与分析了钢的显微组织与磨蚀形貌，研究了新型铸造高铬钢的性能，并对其磨蚀机理进行了较为深入的探讨。试验结果表明，较高的含铬量和含碳量与适量的铜、铜的复合作用，使新型高铬钢具有比高合金化的ＺＳ２８合金更好的抗磨蚀性能，而且成本比较低，具有广阔的应用前景。 In this paper, the chemical composition of a new type of wear-resistant steel for abrasive containing strong acid medium was designed. The microstructure of the steel was observed and analyzed by metallographic microscope, X-ray diffraction, scanning electron microscopy, corrosion and abrasion test, And abrasion morphology, the properties of the new cast high-chrome steel were studied, and the abrasion mechanism was discussed in more depth. The experimental results show that the higher chromium content and carbon content with the appropriate amount of copper and copper compound the new high-chromium steel has better wear resistance than the high alloyed ZS28 alloy, and the cost is relatively low, with Broad application prospects.
