摘要

本文研究了氮碳共渗处理对AISI 1045钢摩擦学性能的影响。这种中碳钢由于其良好的机械性能和较低的成本而被用于汽车工业，尤其是机械部件的制造。通过光学显微镜（OM）、维氏显微硬度测试、扫描电子显微镜（SEM）和销盘式磨损机对处理后的样品表面层进行了表征。实验结果表明，580°C氮碳共渗处理形成的表面层（复合层和扩散区）提高了显微硬度。研究还发现，氮化处理降低了摩擦系数，提高了耐磨性，氮化10小时后，比磨损率降至1/9。

INVESTIGATION OF THE EFFECT OF NITROCARBURIZING TREATMENT ON TRIBOLOGICAL PROPERTIES OF AISI 1045 MEDIUM CARBON STEEL

In this paper, the effect of nitrocarburizing treatment on tribological properties of AISI 1045 steel was investigated. This medium carbon steel was used in automotive industry, especially in the manufacture of machine components due to the good mechanical properties and lower cost. Characterization of the surface layer of treated samples was made by optical microscopy (OM), Vickers microhardness test, scanning electron microscope (SEM), and pin-on-disk wear machine. Experimental results showed that the surface layers formed through nitrocarburizing processing at 580 °C (compound layer and diffusion zone) increased the microhardness. It was found also that the nitriding treatment reduced the friction coefficient and improved the wear resistance, where the specific wear rate were decreased to 1/9 was noticed after 10 hours of nitriding time.
