Effect of TiO2 addition on the microstructure and nanomechanical properties of Al2O3 Suspension Plasma Sprayed coatings
Alumina-titania coatings are widely used in industry for wear, abrasion or corrosion protection components. Such layers are commonly deposited by atmospheric plasma spraying (APS) using powder as feedstock. In this study, both Al2O3 and Al2O3-13 wt% TiO2 coatings were deposited on austenitic stainless steel coupons by suspension plasma spraying (SPS). Two commercial suspensions of nanosized Al2...
متن کاملMicrostructure and Properties of Plasma Sprayed Nanostructural ZrO2 Coatings
Plasma sprayed zirconia deposits have been employed in wide applications for thermal protection. Recently, the use of nanostructural surface represents an alternative for improving the performance of these coatings. The present paper reviewed the works in this field at our research group, including synthesis of nanostructural ZrO2 powders, influence of spraying parameters on microstructure and ...
متن کاملEffect of Carbide Particle Size on the Microstructure, Mechanical properties, and Wear Behavior of HVOF-sprayed WC-17% Co Coatings
This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...
متن کاملMicrostructure and Microwave Absorption Properties of Flame Sprayed Ceramic Coatings
In this research work, airplane grade aluminum alloy substrate was coated by Al2O3/ TiO2 ceramic coatings in two different compositions as 50:50 and 87:13 using Flame spraying technique. The surface & cross-sectional morphological characterizations of the Al2O3/ TiO2 powders and coatings were performed by scanning electron microscopy (SEM). The microwave absorbing properties of coatings were ex...
متن کاملThermal Sprayed Coatings Used Against Corrosion and Corrosive Wear
Coatings have historically been developed to provide protection against corrosion and erosion that is to protect the material from chemical and physical interaction with its environment. Corrosion and wear problems are still of great relevance in a wide range of industrial applications and products as they result in the degradation and eventual failure of components and systems both in the proc...
