Wear and Corrosion Resistances of Oxide Coatings formed on Magnesium Alloys by Micro Arc Oxidation

TEKİN, Mustafa | TAŞLIÇAY, Cengizhan | MUHAFFEL, Faiz | ÇİMENOĞLU, Hüseyin

In the present study, wear and corrosion resistances of magnesium alloys are analyzed after coated by micro arc oxidation (MAO) process for protection of gear component, which is the most wearing part of a bicycle. Two of the most common magnesium alloys (AZ31 and AZ91) were used in the study and they were oxidized in three different electrolytes (aluminate-, silicateand phosphate-based). Scanning electron microscope (SEM) is utilized in order to analyze the coating morphology and wear scars obtained during wear tests. Energy dispersive X-ray spectroscopy (EDS) analyses were implemented to det ...Daha fazlası

Methylene Blue Removal By Phase Separated Porous Glass

ERTUŞ, Emre Burak | AHMETOĞLU, Çekdar Vakıf | ÖZTÜRK, Abdullah

In this study, it was aimed to utilize Porous glass (PG) as an adsorbent in MB removal from wastewater. PG powders were produced by melting and phase separation of an alkali borosilicate glass followed by selective leaching in HCl and an additional alkali treatment. The scanning electron microscope and N2 adsorption/desorption techniques were applied to characterize the pore architecture of the PGs. Methylene blue (MB) adsorption efficiency was investigated from the change in MB concentration in the MB aqueous solutions with various concentrations through the absorbance of the solution at a wa ...Daha fazlası
