The ICME (Integrated Computational Materials Engineering) is an efficient tool that combines key experiments with simulations during the whole R&D process of CVD hard coatings. In this work, MTCVD (Moderate Temperature Chemical Vapor Deposition) Ti(C,N) coatings are developed through ICME, i.e. by the integration of thermodynamic calculations and computational fluid dynamics (CFD) simulations with key experiments. The thermodynamic calculations predict that higher deposition temperature leads to higher C and N contents but lower Ti content under constant gas concentration and pressure. CFD simulation indicates that the deposition rate decreases from inside to outside on the same graphite tray. The deposition rate of the upper trays is higher than that of the lower ones at the outside location of trays. MTCVD Ti(CN) coatings were deposited at three different temperatures to verify the chemical compositions and deposition rates predicted by thermodynamic calculations and CFD simulations, respectively. The experimental investigations are in reasonable agreement with both the thermodynamic and CFD predictions. The present work provides a novel strategy for the rapid development of new type of MTCVD Ti(C,N) coatings and other CVD coatings with industrial applications.
