| Abstract: | The titanium metallized film on A1N ceramic surface was produced by disproportionation reactions. An orthogonal experiment was designed to determine the influences of the reaction time, reaction temperature and the initial concentration of potassium fluorotitanate(K2TiF6%)in salt on process conditions. Through the experiment, the best process condition was determined. The composition of the coating layers, the microstructure and interface between the film and ceramic substrate were characterized by XRD, SEM. The reaction mechanism between A1N and Ti deposited by disproportionation reaction method was discussed. |
