Effect of morphology and nonbounded interface on dielectric properties of plasma sprayed BaTiO3 Coating
In this research, BaTiO3 thick deposit has been successfully sprayed by air plasma spray. The microstructure and dielectric properties of thick films were investigated by secondary electron microscopy (SEM) and LCR meter respectively. XRD measurement was carried out on plasma sprayed BaTiO3. The results illustrate differences in the crystal structure between plasma sprayed coatings and feed sto...
متن کاملThe Effect of Zircon on Long-Time Corrosion Resistance of Alumina
Corrosion resistance of zircon reinforced alumina refractories has been carried out through static crucible test. The corrosion measurements with percentage, the penetration depth of molten steel and the microstructure of the refractories were evaluated after soaking 150 h at the temperature of 1500˚C. Results showed that the corrosion resistance of alumina increased by adding 20 wt% zirc...
متن کاملPreparation ZrO2 ceramic coating by electrolytic plasma oxidation and study of the effect of monoclinic/tetragonal phases on the corrosion resistance of the coating
In this paper, zirconium oxide ceramics coating (ZrO2) were produced on Zircaloy-4 alloy using plasma electrolytic oxidation (PEO). Sodium silicate and Sodium aluminate based electrolyte was selected in PEO process and the effects of the concentration of Sodium aluminate (0, 2.5, 5, 7.5, and 10 g/L) on the microstructure, phase structure and the behavior of corrosion of formed coatings. In orde...
متن کاملPost Heat Treatment of Plasma Sprayed Pure and Alumina-Titania Reinforced Hydroxyapatite Coating on SS 304 Steel
It has been reported by previous research work that in plasma spray process hydroxyapatite decomposes into some amorphous phases due to rapid cooling of the coated substrate during the coating process, which causes instability of coated implant. Post coating heat treatment has been expected to minimize these phases and also enhance the long term reliability of hydroxyapatite coatings on metal s...
متن کاملAlumina nanostructured coating for corrosion protection of 316L stainless steel
Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were analyzed using XRD and SEM. Topography and thickness of coat...
