由于冲压加工的高速化和被加工材料的高强度化,为防止模具磨损、烧伤,实施CVD(化学气相沉积法)的TiC涂层表面处理是有成效的。此方法不仅能延长模具寿命,且能提高制件质量,实现合理化生产和降低成本。最近TiC、TiCN复合涂覆也有所增加。本文以TiC为中心,介绍其原理、方法和应用上的注意点。一、CVD的原理 CVD法将含有金属或非金属化合物的蒸气,由输送气体控制器进入加热的基体表面产生 TiC coating surface treatment by CVD (Chemical Vapor Deposition) is effective in order to prevent mold abrasion and burns due to the high speed of press working and the strength of the material to be processed. This method can not only extend the life of the mold, and can improve the quality of parts, to achieve rationalization of production and reduce costs. Recently TiC, TiCN composite coating also increased. In this paper, TiC as the center, introduces the principle, method and application of attention points. First, the principle of CVD CVD method will contain a metal or non-metallic compounds of the vapor from the controller to send gas into the heated substrate surface generated
