摘要
本文探讨了3Cr_(2w8v)钢经气体软氮化再中频感应加热淬火的组织和性能。试验表明复合热处理的试样截面硬度较高,硬度梯度平缓,与正常淬火、软氮化及中频淬火相比具有较高的耐磨性和抗回火稳定性。软氮化后中频淬火是提高3Cr_(w8v)钢抗回火稳定性和耐磨性的一种可行途径。
The structure and propertis of 3 Cr_2W_8V steel combined treated were studied in this paper. The experimental resu—Its show that the combined treatment can greatly increase the hardness of cross—seetion, and make hardness gradient decrease slowly. By used combined treatment method, hweara—bility, temper stability were increased in comparison with nomal ardening method, nitrocarburising and medium frenquency handening method.
