摘要
根据温度、氧电势实测数据及化学平衡原理 ,对气体渗碳排气过程进行了分析讨论。认为排气阶段的主要作用是零件表面氧化物的还原及消耗降低炉内氧化性气氛的含量 ,而且升温速度对缩短排气时间有重要影响。
The paper analyses and discusses discharge processingas carburizing with data of temperatures,oxygen potentials measured and principle of chemical balance.The author thinks that discharging fumes reduce oxide,consume and decrease the content of oxide atmosphere on the surface of the part.And the speed of raising temperature has an important effect on shortening discharge time.The result will take active action on improving discharge techniqus in gas carburizing.
