Abstract

Abstract:

Sand erosion in aero-engine compressor blades leads to performance degradation and life reduction of aero-engines. Erosion-resistant coatings effectively improve the resistance of compressor blades to sand erosion， but the introduction of hard coatings reduces the fatigue performance of metal blades. TiN single-layer coating and TiN/Ti multilayer coating with the same thickness were deposited on the surface of TC4 titanium alloy by ion plating technology. The surface and cross-section morphologies as well as the basic mechanical properties were characterized by scanning electron microscopy， nanoindentation and X-ray stress analyzer. The rotating bending fatigue performance of TC4 substrates with different coatings as well as without coatings were comparatively analyzed， and the mechanism of TiN and TiN/Ti coatings on the fatigue performance of TC4 substrates was discussed and analyzed. The results of rotating bending fatigue tests showed that the median fatigue strength of TC4 titanium alloy substrate was 530.5 MPa under one million cycles， while the median fatigue strengths of TC4 titanium alloy specimens deposited TiN and TiN/Ti under this condition were 529.2 MPa and 492.5 MPa， which decreased by 0.24% and 7.16%， respectively. The mechanism by which coatings impair the fatigue performance of the substrate is that the cracking of coatings accelerates the fatigue failure of the substrate. Moreover， compared to TiN/Ti coating， TiN coating with lower surface roughness and higher residual compressive stresses causes less damage to the fatigue performance of the TC4 titanium alloy substrate.

Key words: TiN coating, TiN/Ti coating, TC4 titanium alloy, ion plating, fatigue performance
