用20CrMnTi和20CrMo钢制的试样，根据渗碳层深度分别为1.2mm和1.4mm的齿轮的技术要求，在装备有气体渗碳动态碳势控制CAD软件的渗碳炉上分别进行了试验，对模拟结果进行了验证，证实了该软件功能强劲、控制准确。其表面碳浓度(质量分数)偏差＜0.05%；渗层内的碳浓度梯度曲线平滑，呈“S”型平台分布；渗层深度为1.2mm和1.4mm时，渗层深度的偏差＜0.05mm。用该软件设计的渗碳工艺与实际检测结果能很好地吻合。

According to technical requirement of 1．2mm and 1．4mm carburizing depth， steel 20CrMnTi and 20CrMo test pieces were carburized in Unicase furnace with a gas carburizing dynamic control CAD system．The results show that this system has a powerful function and control exactly，the deviation of surface carbon concentration is less than 0．05％（weight），carbon concentration gradient curve in carburized layer is smooth and shows “S” shape，the deviation of carburizing depth is less than 0.05mm when the carburizing depth is 1.2mm or 1.4mm．The experimental results are fit well with that designed by software system．
