چکیده انگلیسی
YSZ/(Ni, Al) composite coatings were deposited on Inconel600 superalloy with ball peening (BP) and without (non BP) treatment using the electrophoretic deposition (EPD) technique, followed by vacuum sintering method. The structures and phase evolution of the coatings were studied with X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The relation between microstructures and properties of the BPs-coated samples was discussed. The results show that the adhesion strength and gain mass of the BPs-coated samples with isothermal oxidation at 1100 °C for 100 h are 3.3 N and 0.00817 mg/cm2, respectively, while those of the non-BPs-coated sample are 2.6 N and 0.00559 mg/cm2, respectively. The EDS mapping analysis indicates that an obvious outward diffusion of Cr from the substrate to BPs coated samples occurs after isothermal oxidation. The BPs-coated sample shows the superior adhesion and oxidation resistance compared with non-BPs-coated samples.
