Texture Analysis in Alumina Plasma Sprayed Coatings
An original investigation of the crystallographic texture in alumina plasma sprayed coatings has been made by X-ray diffraction and transmission electron microscopy. A fibre texture has been revealed in these alumina coatings. The (100) base plane of γ Al2O3 is predominently parallel to the. coating surface. The texture intensity increases from the surface in contact with the metal to the top surface of the coatings. After annealing the textured γ Al2O3 coatings at 1200℃, we have studied the relationships between γ and α Al2O3 phases.
