离子化学热处理(渗氮、碳氮共渗、渗碳)适用于机器钢件、铸件以及工具的表面强化。离子化学热处理的准备工序包括机械清理零件表面、去油污(如用8％浓度的TMC—31号水溶液在60～70℃水温下进行)、热水冲洗以及用热空气烘干或在室温下凉干。离子化学热处理有一系列处理工序,其中首要的是在辉光放电后马上利用微电弧清除零件上的有机物残余(油污、乳化剂等)。根据零件的多少(即零件的总面积)以及零件的污垢程度,清除时间为0.5小时到4小时不等。随着清除上序的进行,零件的温度上升到250～280℃。由于去油污及冲洗后一般在清洗剂难接触的地方(如中心处,孔洞、沟 Ion chemical heat treatment (nitriding, carbonitriding, carburizing) is suitable for surface strengthening of machine steel parts, castings and tools. Preparations for ion-chemical heat treatment include mechanical cleaning of part surfaces, degreasing (eg, using a TMC-31 aqueous solution at a concentration of 8% at a water temperature of 60-70 ° C), hot water rinsing, and drying with hot air or at room temperature dry. Ion chemical heat treatment has a series of processing steps, the first of which is the use of micro arcs to remove organic residues (oil, emulsifiers, etc.) from the part immediately after the glow discharge. Depending on the number of parts (ie, the total area of ​​the part) and the degree of dirt on the part, the clearance time varies from 0.5 hour to 4 hours. With the removal process, the temperature of the part rises to 250-280 ° C. As to the oil and rinse generally difficult to contact with the cleaning agent (such as the center, holes, ditches
