Abstract: To clarify the application feasibility of TW-7(A) coating (without surface layer) on GH2150A high-pressure compressor rotor blades, systematic tests including 600 ℃ salt-coated thermal corrosion test, simulated deck parking environment accelerated corrosion test, and room-temperature vibration fatigue test (with pre- and post-corrosion comparison) were carried out to study the corrosion protection performance of the coating and its influence on the fatigue strength of blades. The results show that the TW-7(A) coating effectively protected the GH2150A matrix through the cathodic protection mechanism of a sacrificial anode, exhibiting excellent corrosion resistance. Meanwhile, the coating could improve the median vibration fatigue strength of the blades to a certain extent, with a small attenuation amplitude (about 4.5%) after corrosion. Based on the comprehensive performance indicators, the TW-7(A) coating could be used as the preferred corrosion protection coating for GH2150A high-pressure compressor rotor blades.
