45钢氮基气氛软氮化冷却方式对处理表面摩擦学性能的影响

The Influence of Cooling Ways on the Tribological Properties of 1045 Steel Surface Treated by N 2 Base Soft Nitriding

利用球—盘摩擦磨损试验机，研究边界润滑条件下４５钢氮基气氛软氮化冷却方式对处理表面摩擦学性能的影响，并利用Ｘ射线衍射仪、扫描电子显微镜（ＳＥＭ）和波谱仪（ＷＤＸ）对处理表面的相组成和成分进行了分析。结果表明，空冷较炉冷因所获软氮化层的氧化膜增多，从而摩擦学性能显著提高。

The influence of cooling ways on the tribological properties of 1045 steel surface treated by N 2 base soft nitriding was investigated under boundary lubrication on a “ball-on disc”testing machine. The results show that cooling in the air is better than cooling in a stove with regard to the tribological properties of 1045 steel when its surface is being treated by N 2 base soft nitriding. The X - ray diffraction, Scanning Electron Microscope(SEM),Wave Disperison X-ray Spectrometer(WDX)were used in phase analysis and composition analysis of the treated surface.
