摘　　要：热梯度CVI工艺(TCVI)是制备C/C复合材料的一种高效工艺。该工艺致密化机理比较复杂,影响控制效果的因素较多,实现自动化监控较为困难。本文在分析TCVI工艺流程的基础上,提出了沉积工艺控制方案,并利用工业控制组态软件K ingview 6.5开发了TCVI工艺监控系统,可以实现对工艺过程的自动控制。Temperature grade CVI process （TCVI）is a highly efficient method for manufacturing C/C composites. Its mechanism for density formation is very complex and many factors are involved in influen- cing control effects, thus being difficult for the process to realize automatic supervisory control. By analyzing the characteristics of the TCVI process, the paper presents a control scheme. The supervisory control system of TCVI is developed by using the software Kingview 6.5 so as to realize its automatic control.
