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 کاملUse of natural coagulants for industrial wastewater treatment
Industrial effluents are a menace to the environment and the fact that their characteristics vary from industry-to-industry only adds to the complex challenge they offer to the engineers and scientists. Resource-efficient and environment-friendly solutions to this hazard are a call of the hour. Coagulation, by synthetic chemicals, has been used as a cost-effective and efficient method for manag...
متن کاملScope of biological treatment for composite tannery wastewater
Tannery wastewater is heavily polluted containing appreciable biodegradable matters as well as inorganic substances like chromium, sulphide, chloride etc. Thus the composite tannery wastewater appears to be incompatible for direct biological treatment .Wastewater emanated from various sub-processes of tannery operation showed variable characteristics and also differential treatability. The pres...
متن کاملThe elimination of chromium in the treatment of tannery industrial wastewater
Presents the findings of a study conducted to examine the efficiency of the combined anaerobic-aerobic reactors for the treatment of three different tannery industrial wastewaters, focusing on the fate of chromium and other associated metals. Examines elimination rates of such metals with respect to each successive treatment process. Discusses the correlation between the chemical characteristic...
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 ...
