The abradable coating is one of the significant stator components in aero-engine,which protects the rotating blade and casing by abrading itself and improves the engine performance by reducing the gap between the rotor and stator. In this study,taking the addition-type silicone resin as the matrix,the effect of diameter and stacking density of glass hollow/solid microspheres on the processability of abradable coating was investigated. Moreover,the effect of glass microsphere type and content was illustrated using a self-designed wear tester simulating the working conditions of stator in aero-engine. The results show that the silicone resin reinforced by H-type (size distribution 20–820 um) hollow glass microspheres exhibits excellent surface quality,flowability and comprehensive performance. The suitable preparation technology of abradable coatings was developed by glass microsphere selection,content controlling,tool design and infusion parameters optimizing. The as-prepared glass microsphere/silicone abradable composite is successfully applied and verified in aero-engine stator component.
