资源简介：
The TiB2 coating deposited by magnetron sputtering on the Ti6Al4V-simulated blade tip with a dense fiber-like microstructure has the adhesion strength grade of HF1. High-speed rubbing results showed that the TiB2 coating could inhibit the adhesive transfer of the Al-hBN seal coating at 300 m/s. It was found that the tribological oxidation of TiB2 coating led to the TiB2/fused Al interface reaction by characterization of the interface microstructure of the Al-adhesive blade tip. The thin interface reaction interlayer mainly consists of TiAl3 phase. The large thermal stress at TiAl3/TiB2 interface makes the interface reaction layer with the Al-adhesive transfer layer easily peel off from the blade tip. Thus, the Al-adhesive transfer is always at a lower level.
