304不锈钢双活性屏离子渗氮
Double Active Screen Plasma Nitriding of 304 Stainless Steel
摘要
Abstract
Objective To explore the feasibility and thermal effectiveness of double active screen plasma nitriding ( DASPN) of 304 stain steel. Methods Nitrided layers were prepared on 304 stainless steel substrate by low terperature DASPN technique and common direct-current plasma nitriding ( DCPN) technique, respectively. The morphology, phase structure, hardness and corro-sion properties of the nitrided layers were comparatively analyzed. Results The nitrided layer produced by DASPN technique was more homogenous and compact compared with that produced by DCPN. It was a single S-phase layer and the hardness of the layer was 763HV0. 25. Moreover, the layer had a better corrosion resistance than that produced by DCPN. Conclusion The thermal ef-fectiveness of 304 steel by DASPN technique was better than that of DCPN treatment, which is probably applicable to commercial process.关键词
