非调质钢 35MnVN 磨粒磨损特性的研究

RESEARCH ON ABRASIVE WEAR OF MICROALLOYED MEDIUM CARBON STEEL 35MnVN

研究了非调质钢３５ＭｎＶＮ强化状态（淬火＋低温回火）的磨粒磨损特性，并选取４０Ｃｒ、４５号钢调质后强化处理状态作了磨损性能比较。结果表明：３５ＭｎＶＮ钢组织中的沉淀相对提高耐磨性有益；与４０Ｃｒ、４５号钢调质后强化态的耐磨性相比，３５ＭｎＶＮ强化态的耐磨性基本与其相当。

The abrasive wear of a microalloyed medium caborn steel 35MnVN in a hardened state is studied in this paper, and compaired with those of quenched and tempered 40Cr、45 steels in hardened state. The results show that: precipitate particles in 35MnVN have a good contribution to wear resistance of the steel. The abrasive wear resistance of 35MnVN in hardened state is almost the same as those of 40Cr、45 steels.
