摘要
本文主要对W13Cr4V钢高浓度碳氮共渗后的渗层成分、显微组织、硬度分布、共渗时间对渗层深度的影响以及实际使用效果等进行了研究分析;并对高浓度渗碳某些规律问题进行了探讨.研究结果表明,W13Cr4V钢制黑色金属冷挤压模经高浓度碳氮共渗一直接淬火,低温回火后,可显著提高其表面硬度、耐磨性和抗咬合性能,使用寿命比常规热处理可提高4～5倍。
Having applied and studied the carbonnitriding process to a cold extruding die of high speed steel W18Cr4v,the author describes the composition, microstructure,hardness gradient of the carbonnitrided layers,the influence of carbonnitriding duration on the depth of layers and aiso the practical effectiveness in its service.The experimental results show that the surface hardness,Wear resistance,and anti-seizing Properties are increased and improved,and the life of its service may be increased by 2—3 times in comparison with what has been normally treated.
