研究了利用熔盐热析出反应法对AlN陶瓷的表面金属化. Ti金属化涂层呈现TiO/TiO_1-x/TiN层状结构,在涂层与AlN陶瓷结合处,存在TiN和AlN的梯度复合结构.研究表明,金属化处理显著改善了AlN陶瓷表面与金属Al的润湿性能,在1000℃下,润湿角从114.4°降至49.7°.

Ti metallized coating was prepared on AIN surface by the molten salt reaction method. The graded composite of TiN and AIN was observed near the interface between the coating and AIN. The result shows that the coating has the TiO/TiO_1-x/TiN laminar microstructure. The wettability of AIN surface with Al is improved by metallization and the contact angle is decreased from 114.4° to 49.7° at 1000℃.
