The intermetallic compound Al3Ti is tested for metallization of the ZrO2 and Al2O3 ceramics. For ZrO2, the contact angle of Al3Ti melt is of 35°, and for Al2O3, it is of 47°. Metallization is carried out by both infiltration of titanium powder layer applied on the ceramic surface with molten aluminium and further heating up to melting of formed Al3Ti. The coating with high adhesion to ceramics is obtained for ZrO2 ceramics, which can withstand heating in air up to 1000°С for 60 min. For Al2O3 ceramics, results are much worse, probably, due to high deoxidation of the interface.

Key words: metallization, zirconia, alumina, Al3Ti, wetting, infiltration, heat resistance.
