Abstract: 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/TiO1-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℃.
