Aluminum alloys have been used in industries for years because of light weight. But these materials have some disadvantages like low mechanical properties. For increasing of the mechanical properties of aluminum alloys can be coated with hard ceramics. In this study, T6 heat treated 6063 aluminum alloy were coated with %8 Y-PSZ powders by plasma spraying method. Subsequently, creep properties of the uncoated and coated samples were investigated. Temperature dependent creep tests were carried out at 100, 125, 150 degrees C temperatures and at 170 MPa stress conditions. Stress dependent creep tests were carried out at 120, 145, 170 MPa stresses and at 100 degrees C temperature conditions. The creep results of the uncoated and coated samples were discussed and compared.
