本文主要介绍在研制成的等离子渗碳装置上进行渗碳试验。试验表明在900℃处理时,面层含碳量为0.85～1.05％,层深1毫米所需时间仅为1.5小时,比普通气体渗碳能量减少50％,且试样表面光洁。这是一种高效、优质、低能耗的具有较高经济效益的工艺。 This article mainly introduces the carburizing test on the developed plasma carburizing device. Experiments show that when the surface temperature is 900 ℃, the surface carbon content is 0.85-1.05%, the depth of 1 mm is 1.5 hours, and the carburizing energy is reduced by 50% compared with the ordinary gas, and the surface of the sample is smooth. This is a high efficiency, high quality, low energy consumption with high economic benefits of the process.
