Visible Domain Photocatalysis Performance of Ti-Si Thermal-Sprayed Coatings

چکیده
Cost and performance-effective materials used in advanced oxidation processes such as photocatalysis have obtained widespread attention recent years. In this study, thermal spraying was a one-step method to obtain thick visible-light-active photocatalyst coatings on two types of substrates, namely, plain carbon steel copper. A mixed metallic titanium–silicon powder bearing 10% wt. Si feedstock. The optical bandgaps the were close 1.000 eV, allowing good photodecoloration efficiencies (>89%) mineralization (>67%) for methylene blue dye from aqueous solutions under visible light irradiation. photodegradation process could be successfully modelled by Langmuir–Hinshelwood pseudo-first-order kinetic model, with reaction rate constants k between 0.16 1.06 h−1.

Solid Particle Erosion of Thermal Sprayed Coatings
Solid particle erosion is an important material degradation mechanism. Although various methods of coating are tried and used for protection against erosion, thermal sprayed coating for such purpose is the most widely used method. In this chapter, evolution of thermal sprayed coating, erosion testing methods, and erosive wear of thermal sprayed coatings are discussed extensively with emphasis o...
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...

متن کاملBio-tribological properties and cytocompatibility of Ti-Si-N coatings
TieSieN coatings are synthesized on titanium alloy (Ti6Al4V) by arc-enhanced magnetron sputtering and the microstructure and tribological properties are determined. The friction coefficient of the TieSieN coatings, which is smaller in human serum than ambient air, decreases gradually with Si contents. Protein gel electrophoresis shows that the small friction coefficient is due to adsorbed prote...
