氮化工艺(添加或不添加含碳气体的氮化、离子氮化等)能提高切削工具的耐磨性,但这种工艺不足之处是成本高,所用设备复杂并且生产率低。根据这个观点,采用无毒的氰酸盐和碳酸盐对工具钢表面进行低温液体氰化具有无比的优越性。众所周知,这个工艺在苏联叫做氰化。西德叫 Tenifer-1和美国叫 Meloni-te 等等。根据文献报导,很多国家的工厂 Nitriding processes (nitriding, ion nitriding, etc. with or without the addition of carbonaceous gases) can increase the wear resistance of the cutting tool, but the disadvantages of such processes are high cost, complex equipment used and low productivity. According to this view, the use of non-toxic cyanates and carbonates on the surface of tool steel for liquid cyanidation is extremely advantageous. As we all know, this craft is called cyanidation in the Soviet Union. West Germany called Tenifer-1 and the United States called Meloni-te and so on. According to the literature, many countries’ factories
