The reactive plasma spraying at low pressure was used for the synthesis and deposition of titanium carbide enhanced hybrid coating. The commercially available powder Ti was used for this study.The natural gas was used as carrier gas for not only transporting the powders in plasma jet but also for providing the carbon resource. The optical emission spectroscopy was used to demonstrate the chemical species in the plasma and indirectly infer the existence of vapor phase of titanium. The phase and microstructure of the coating were characterized by XRD and SEM, respectively. The analysis results affirm that the titanium carbide phase was formed in the coating and the coatings show a hybrid microstructure TiC/Ti.The abrasive test was also conducted and the result showed that the distribution and the size of titanium carbide particles in the composite coating played an important role in determining the properties of coating abrasion resistance.
