AbstractTo solve the problem of friction and wear of titanium alloy blade in aero-engine compressor, we prepared a Ni-cBN composite coating on Ti-6A1-4V (TC4) substrate with improved bonding strength by composite electroplating combined with the surface activation of the titanium alloy processing. The friction and wear properties of the coating with the Ni-based abradable seal coating were studied by high temperature friction and wear test, and the results were compared with the TC4 rub with Ni-based abradable seal coating. The coating was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The results show that a well bonded composite coating on the TC4 substrate is obtained after surface activation treatment of titanium alloy substrate. The deposited Ni-cBN composite coating exhibits a very strong grinding ability and low friction coefficient, which provides protection for the titanium alloy tips.
