摘要

研究了Fe-19Cr-15Mn-0.66N高氮奥氏体不锈钢(HNSS)的摩擦磨损性能。利用扫描电镜(SEM)和激光共聚焦显微镜(LSCM)研究了不同载荷作用下的磨损机理，并分析了不同载荷作用下材料耐磨性提高的原因。随着载荷的增加，摩擦系数降低，耐磨性提高。在较高载荷下，摩擦增强了HNSS的加工硬化能力，从而提高了其表面硬度，从而提高了HNSS的耐磨性。

Friction and wear behaviors of a high nitrogen austenitic stainless steel Fe-19Cr-15Mn-0.66N

The friction and wear behaviors of a Fe-19Cr-15Mn-0.66N high nitrogen austenitic stainless steel (HNSS) were investigated. Tribological investigations were carried out under different applied loads of 5 N, 10 N, 15 N and 20 N. Scanning electron microscope (SEM) and laser scanning confocal microscope (LSCM) were used to understand the wear mechanisms under different loads and the reasons for the improved wear resistance. The lower friction coefficient and improved wear resistance were observed with the increase in applied loads. Under a higher load, the friction enhanced the work hardening ability of HNSS, which in turn improved its surface hardness and thus the increased wear resistance of HNSS.

期刊介绍： University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded. Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
