本文介绍了利用HG—150A型辉光离子氮化炉进行的灰铸铁硫、碳、氮离子共渗工艺试验。对试样表面渗层的金相组织用光学显微镜进行了观察,并用显微硬度计测试了渗层深度和硬度,还进行了缸套/活塞环的销盘模拟摩擦磨损试验。结果表明,本文介绍的工艺与国内其它工艺相此,有渗层深、保温时间短、抗磨损能力强等特点,具有显著经济效益。 This paper introduces the gray cast iron sulfur, carbon and nitrogen ion osmosis technology test by using HG-150A glow ion nitriding furnace. The microstructure of the coating layer on the surface of the sample was observed with an optical microscope. The depth and hardness of the coating were tested with a microhardness tester. The pin-plate friction and wear test of the cylinder liner / piston ring was also carried out. The results show that this article describes the process and other domestic processes in this regard, there are deep infiltration, holding time is short, strong anti-wear ability, with significant economic benefits.
