摘要/Abstract

摘要： 为了了解深冷处理对DC53冷作模具钢摩擦磨损性能的影响,利用洛氏硬度计、摩擦磨损试验机测试了经不同时间深冷处理的DC53冷作模具钢的硬度和摩擦磨损性能。结果表明,经过深冷处理后,DC53冷作模具钢的硬度变化较小,耐磨性有较大提高。经不同时间深冷处理的DC53冷作模具钢的摩擦磨损性能均优于未深冷处理,增加深冷处理时间并不能进一步提高材料的性能,深冷处理时间为2 h和6 h时材料的摩擦磨损性能较好,与未深冷处理相比,其磨损率分别降低了48.3%和47.0%。

关键词: 深冷处理, 冷作模具钢, 硬度, 磨损率

Abstract: Hardness and friction and wear properties of DC53 cold work die steel with different soaking time were tested by Rockwell hardness tester, friction and wear testing machine to investigate the effect of cryogenic treatment on its friction and wear properties. The results show that, after cryogenic treatment, the hardness of the DC53 cold work die steel changes a little, and the wear resistance is greatly improved. The friction and wear properties of the DC53 cold work die steel cryogenic treated for different time are better than those without cryogenic treatment. Increasing the cryogenic treatment time cannot further improve the properties of the material. The friction and wear properties of the material are better when the cryogenic treatment time is 2 h and 6 h, thereby, compared with the specimen without cryogenic treatment, the wear rate is reduced by 48.3% and 47.0%, respectively.

Key words: cryogenic treatment, cold work die steel, hardness, wear rate
