It is of signific.nc. that the wettability between the molten alloy and the Al2O3affec.s the inc.usion removal,nozzle c.ogging and refrac.ory erosion. In the present work, the wettability between the Al2O3substrate and Fe–P–Ti alloys with different Ti c.ntent was investigated by using the sessile droplets method. The interfac.al c.arac.eristic. were investigated by sc.nning elec.ron mic.osc.pe（SEM）.

The reac.ion between [Ti] and Al2O3substrate in the interfac. results in the formation of Ti-c.ntaining oxides.
