通过等温淬火获得含碳化物等温淬火球墨铸铁(carbidic austempered ductile iron，简称CADI)，并分别在中性、酸性和碱性腐蚀介质中进行腐蚀磨损实验，研究淬火温度对CADI在不同腐蚀介质中耐腐蚀磨损特性的影响，并与低铬铸铁进行对比。结果表明：在酸性和碱性介质中，CADI 的质量磨损随等温淬火温度升高先增加，然后再减少；在中性介质中，CADI 的质量磨损随等温淬火温度升高而逐渐增加；CADI 在酸性介质中的耐腐蚀磨损性能相对较差；CADI在不同pH值溶液中的耐磨损性能均优于低铬铸铁，是一种优良的耐腐蚀磨损材料。

In order to study the effects of austempered temperature on corrosive wear behaviors of carbidic austempered ductile iron (CADI), the CADI was prepared, and the wear corrosion resistance test was conducted in acid medium, neutral medium and alkaline medium, respectively. The results show that in acid medium and alkaline medium, the mass loss of CADI first increased and then decreased with increasing austempered temperature. But in neutral medium, the mass loss of CADI increased gradually with increasing austempered temperature. The performance of corrosion wear resistance of CADI in acid medium is inferior to that in alkaline medium and neutral medium. While the performance of corrosion wear resistance of CADI is obviously superior to that of low chromium white cast iron under different pH values medium. Therefore, CADI is a material with good property of corrosion wear resistance.
