چکیده انگلیسی
Ceramic coatings of alumina, titania, chromia, alumina-13 wt% titania and zirconia powder were deposited on steel substrate using atmospheric plasma spraying technique. The coatings were characterized for their cross-section, surface morphology, phase composition, indentation fracture toughness, elastic modulus and residual stresses. The nanoscopic features of some coatings were captured using transmission electron microscopy. The coating porosity was found to depend on the melting point of the powder and also the powder size. Equi-axed grains were found to grow in the plane of the coating. All coatings showed tensile surface residual stress. The magnitude of this stress was found to depend on the elastic modulus of the coating material and coating defect density.
