等离子渗碳是目前继气体渗碳、真空渗碳后所采用的第三种渗碳方法。具有高浓度渗碳、高深度渗碳及对于烧结件和不锈钢的难渗碳件进行渗碳的能力,基本上解决了现有的渗碳处理问题。这里简述一下等离子渗碳的原理、特点以及处理实例和等离子渗碳炉。 1 等离子渗碳的原理和特点 1.1 等离子渗碳的原理等离子渗碳是把丙烷、甲烷及LNG等的渗碳气体保持在1～10托的压力下,通过在阴极处理件和阳极之间加直流电压,且由此而产生的异常辉光放电而进行渗碳。等离子渗碳是在气体渗碳基础上进行的异常辉光放电,由于具有以下特点,所以可以进行快速渗碳。
Plasma carburizing is the third carburizing method adopted after gas carburizing and vacuum carburizing. The ability to carburize high concentration carburization, high degree carburization, and hard carburized parts for sintered parts and stainless steels essentially solves the existing carburizing problems. Here briefly describe the principle of plasma carburizing, characteristics and treatment examples and plasma carburizing furnace. 1 Principle and characteristics of plasma carburizing 1.1 Principle of plasma carburizing Plasma carburizing is the propane, methane and LNG carburizing gas is maintained at 1 ~ 10 Torr pressure, by adding between the cathode treatment and the anode DC Voltage, and the resulting abnormal glow discharge carburizing. Plasma carburizing is an abnormal glow discharge performed on the basis of gas carburizing, which enables rapid carburization due to the following features.
