| Abstract: | Conventional Al2O3-13%TiO2(mass fraction) powder and agglomerated nanostructured Al2O3-13%TiO2 powder were seperately used as the raw materials to prepare two types of ceramic coatings on the surface of TiAl alloy via plasma spraying.The microstructure,adhesion to substrate and erosion resistance of resultant conventional and nanostructured ceramic coatings were comparatively analyzed.Meanwhile,the erosion failure mechanisms of the ceramic coatings were discussed.It was found that as-sprayed conventional ce... |
