This study attempted to manufacture an Y₂O₃ ceramic coating layer on a ceramic (AlN) substrate using aerosol deposition (AD) and investigated its macroscopic properties. Pure Y₂O₃ powder with a polygonal shape and average size of 5.0 μm was used as initial feedstock. Using aerosol deposition with suitable process conditions, an Y₂O₃ coating layer was successfully fabricated on aluminum nitride (AIN). The thickness of the manufactured coating layer was approximately 10 mm. The coating layer consisted of Y₂O₃ phase identical to that in the initial powder, and no additional oxides were identified. In regard to the roughness of the Y₂O₃ coating layer, the average roughness (Ra) measured 1.32 μm, indicating that the surface roughness was relatively even compared to the initial powder size (5 μm). Mechanical properties of the Y₂O₃ coating layer were measured using nano indentation equipment, and the indentation modulus of the Y₂O₃ coating layer fabricated by aerosol deposition measured 136.5 GPa. The interface of the coating layer was observed using TEM, and the deposition mechanism of the Y₂O₃ coating layer manufactured by aerosol deposition was also discussed.
