研究了固溶热处理对高Ｃｒ－Ｎｉ铸造不锈钢耐磨损腐蚀性能的影响，探讨 了钢的磨损腐蚀性能与显微组织、硬度，耐腐蚀性能之间的关系，以及高Ｃｒ－ Ｎｉ不锈钢的磨损腐蚀机制。结果表明：当固溶温度超过１１５０℃后，钢的耐磨 损腐蚀性能才明显增加；钢的耐磨损腐蚀性能与硬度无一致性关系，而与耐 腐蚀性能有一定的相关性；钢的耐磨损腐蚀性能、耐腐蚀性能、硬度均与组织 中析出相的性质和数量有关。
The effect of solution heat treatment on the wear resistance and corrosion resistance of high Cr-Ni cast stainless steel was studied. The relationship between the wear and corrosion resistance of steel and its microstructure, hardness and corrosion resistance was discussed. The wear of high Cr-Ni stainless steel Corrosion mechanism. The results show that when the solid solution temperature exceeds 1150 ℃, the wear resistance and corrosion resistance of steel increase obviously. The wear resistance and corrosion resistance of steel have no consistency with the hardness, but have certain correlation with the corrosion resistance. Wear-resistant corrosion resistance, corrosion resistance, hardness are related to the nature and quantity of precipitation phase in the organization.
