研究了铸造复合中锰奥氏体钢在冲击磨料磨损条件下的耐磨性能。

The iron, in which the carbide has a high chemical stability and the matrix possess a matchable oxidation resistance, can be well resistant to abrasive wear at elevated temperature. In addition, the high temperature abrasive wear resistance of the high Cr—Ni cast iron containing eutectic carbide is much better than that of 0Cr26Ni14 heat resistant steel in which no carbide exists.

结果表明，M〓C〓型碳化物的高温化学稳定性对高Cr—Ni铸铁合金的抗高温磨料磨损性能有显著的影响，碳化物的高温化学稳定性愈好，基体的抗氧化性又能与之相匹配，合金的高温抗磨性就愈好；而且，含有碳化物的高Cr—Ni铸铁合金的高温抗磨性远优于不含碳化物的0Cr26Ni14耐热钢。
