In the present work, the wettability between the Al2O3 substrate and Fe–P–Ti alloys with different Ti content was investigated by using the sessile droplets method. The interfacial characteristics were investigated by scanning electron microscope (SEM). The contact angles between the sintered Al2O3 substrate and Fe–P–Ti alloys with 0, 0.05, 0.10 and 0.15 wt% Ti are 100.1°, 97.3°, 94.5° and 90.5°, respectively.

With the increase of Ti content in the Fe–P–Ti alloys, the formed oxides change from Al2O3 to Ti-containing oxides.

The quantity of the interfacial oxides increases with the increase of Ti content in the alloys.

The microstructure of different types of inclusions was observed using three-dimensional analysis techniques. Research has found that the oxygen content before aluminum addition has no significant effect on the final oxygen content. However, under low aluminum and low oxygen conditions, the size of inclusions formed is small and difficult to float and remove. Even if the cycle time is extended, the AF index of inclusions remains at a high level. Through three-dimensional morphology analysis of inclusions, it was found that alumina formed under high aluminum and high oxygen conditions is very dense, while inclusions are relatively loose under low aluminum and low oxygen conditions. In addition, through the analysis of aluminum oxygen supersaturation before the formation of aluminum oxide inclusions, it was found that due to the low oxygen content, the nucleation rate of aluminum oxide in the early stage of inclusion formation is relatively low, and the inclusions grow along the trajectory of oxygen, ultimately forming polycrystalline aluminum oxide inclusions.
