要求耐磨、抗疲劳、心部有良好强韧性的零件,常采用低碳钢或低碳合金钢进行碳氮共渗。碳氮共渗剂常用氨+煤油,甲醇+尿素+丙酮和三乙醇氨等。这些共渗剂存在着附加设备多,原料供应困难,易出现黑色组织,氮浓度低,价格昂贵等缺点。我们使用酒精+水溶入尿素配制的溶液和煤油作为碳氮共渗剂。用300ml酒精加90ml水代替甲醇作载体气,在获得同样的产 Requirements of wear-resistant, anti-fatigue, the heart has good toughness parts, often using low-carbon steel or carbon steel for carbonitriding. Carbonitrides common ammonia + kerosene, methanol + urea + acetone and triethanolamine and so on. These infiltrating agents have many additional equipment, raw material supply difficulties, prone to black tissue, low nitrogen concentration, high price and other shortcomings. We use alcohol + water dissolved in urea solution and kerosene as carbonitriding agent. With 300 ml of alcohol plus 90 ml of water instead of methanol as carrier gas, the same yield was obtained
