AbstractAs the number of aircraft that park in ocean environments increases, the corrosion of coatings used in their engines becomes inevitable. Previous studies have focussed on the abradability of as-sprayed seal coatings in high-speed rubbing tests with a blade. This study deals with the investigation of the effect of corrosion on the abradability of seal coatings. It uses metallographic analysis and hardness, bonding strength and high-speed rubbing tests conducted on as-sprayed and corroded Al-hBN coatings. The results have shown the appearance of additional pores in the corroded coatings and a decrease in the coating mechanical properties. Compared with the as-sprayed coatings, the corroded coatings caused an increase in blade wear and severe overheating of the blade tip during the high-speed rubbing test when the rubbing speed and single-pass depth were high. The unfavourable thermal properties of the corroded coatings were considered as the probable reason for these results.
