1.绪论气体渗碳具有可以改变碳势之优点。但是,过去用发生器制备运载气氛的方法却有设备昂贵、难以控制、燃料用量大、占地面积大、修理时间长等缺点。因此,不用发生器而使有机液体直接在渗碳炉内分解成适当气氛的滴注式气体渗碳法,正在开始采用。在渗碳剂方面,研究了各种有机液体。但是,松节油、苯、醇、乙二醇、酮、酯、醚、 1. Introduction Gas carburization has the advantage of changing the carbon potential. However, in the past, the method for preparing a carrier atmosphere by using a generator has the disadvantages of expensive equipment, difficult control, large amount of fuel, large floor space and long repair time. Therefore, a drip gas carburizing method in which an organic liquid is directly decomposed into an appropriate atmosphere in a carburizing furnace without a generator is being started. In the case of carburizing agents, various organic liquids have been studied. However, turpentine, benzene, alcohols, glycols, ketones, esters, ethers,
