Effects of Substrate Temperature during Thermal Spray Deposition on Mechanical Properties of Ceramic Coating

摘要：

Mechanical properties of thermal-sprayed ceramic coatings were investigated. Al2O3 and Y2O3-stabilized ZrO2 (YSZ) coatings were deposited on plate substrates. Stainless steel plates and aluminum plates, of different thermal expansion coefficients, were used as substrates. The coatings were prepared at two different thicknesses. During deposition of each sample, the history of substrate temperature was recorded. Four-point bending tests were carried out, while strains at the coating surface and the substrate surface were measured with strain gages. The apparent Youngs modulus of the coating was determined using the composite beam theory. In addition, the rupture strain of the coating was measured by three-point bending test. The relationships between the results of these tests and the each substrate temperatures during deposition were discussed.
