兩种表面热处理液体滲氮及滲硫工艺与現行生产上原采用之液体渗炭淬火处理工艺,在尽量保持其他可变数不变的情狀下加以比較。在试样磨損試驗及钢領运轉試驗中,都曾显示滲炭后再滲入氮及硫较之滲炭淬火钢领有較好的耐磨性,較短的走熟期,較長的寿命及少得多的断头率。其中硫化处理显示最佳的效果。 Two kinds of surface heat treatment of liquid nitriding and sulfur infiltration process with the current production of the liquid carburizing quenching process used in the original, as far as possible to maintain other variable under the same circumstances to be compared. In the sample wear test and the ring running test, it has been shown that the infiltration of nitrogen and sulfur after carburizing has a better wear resistance than that of the carburized and hardened steel, the short maturity, long life And much less broken rate. Sulfidation shows the best result.
