摘要
本文介绍了经深冷（－１９６℃）处理的４５＾＃钢的性能：同淬火钢相比，其硬度从ＨＲＣ５１－５５降到ＨＲＣ４９－５１，而在干摩擦和２０＾＃机油润滑条件下，其耐磨性能提高２－６倍。金相分析表明，是白亮层的存在改进了淬火钢的耐磨性能。
The performances of steel45# being cryogenic tremtment are introduced in the paper. Compered with quencbed steel, the bardness decreased from 51-55 to 49-51, while wear resistance increased by 2-6 times after crygenic treatnent. It is the albescert lay-er (about 30μm) which improves the wear resiatance perfornences of quenched steel after cryogenic treatment.
