摘要	The Al-hBN seal coating invariably transfers to the tip of the Ti6Al4V blade under high-speed rubbing, resulting in the deterioration of the power and the reliability of the developed aero-engine. The Al-adhesion phenomenon was reproduced using a high-speed rubbing test rig at 90 m/s and 300 m/s. The results showed that the coverage rate and thickness of the Al-adhesive transfer layer were higher at 300 m/s than at 90 m/s, which could be attributed to the Ti-Al interface reaction. The interface microstructure and the thermal stress distribution model were proposed to reveal the mechanism of the Al-adhesive transfer under conditions of high-speed rubbing. A gradient interface reaction interlayer composed of TiAl3 and gamma-TiAl between the Al -adhesive transfer layer and the Ti6Al4V blade tip was observed only at 300 m/s. This interface reaction interlayer could release the thermal stress and enhance the adhesion between the Al -adhesive transfer layer and the Ti6Al4V blade tip.
