【摘要】：通过室温化学渗硫技术在45钢表面制备渗硫层,采用M-200型摩擦磨损试验机评价了渗硫层在定载荷和变载荷下的摩擦磨损性能,用扫描电子显微镜、三维轮廓仪和X射线衍射仪观察分析了渗硫层的形貌、结构、物相组成及其磨痕形貌。结果表明,渗硫层摩擦过程中硫元素会向对偶件扩散,并生成具有润滑作用的氧化物,摩擦系数一直很小。渗硫层减摩耐磨效果明显,有效改善钢的粘着磨损特性。
[Abstract]:The sulphurizing layer was prepared on the surface of 45 steel by chemical sulphurizing technology at room temperature. The friction and wear properties of the sulfurized layer under constant load and variable load were evaluated by using M-200 friction and wear tester, and scanning electron microscope (SEM) was used. Three-dimensional profilometer and X-ray diffractometer were used to observe and analyze the morphology, structure, phase composition and wear trace morphology of the sulfurized layer. The results showed that the sulfur element diffused to the dual part during the friction of the sulfurizing layer, and the oxide with lubricating effect was formed. The friction coefficient is very small all the time. The friction and wear resistance of sulphurized layer is obvious, and the adhesion and wear characteristics of steel are improved effectively.
