Corrosion & Surface Treatment

Abstract
Pure Mg, Mg-5wt%Ca, and Mg-5wt%Ca-1wt%Zn alloys were cast, and their high-temperature oxidation behavior was investigated to determine the roles of Ca and Zn in oxidation. Ca and Zn additions refined the microstructure by formation of Mg₂Ca and Ca₂Mg₆Zn₃, respectively, at grain boundaries. Ca increased the oxidation resistance by forming a..... More

Material Analysis & Characterization

Abstract
In order to strengthen the structure of the glass and ultimately improve its water resistance, P₂O₅–ZnO–Bi₂O₃ was doped with Fe₂O₃, which generated Fe ions in the phosphate-based glass. These ions constitute (P₂O₇)⁻⁴ groups within the glass network. Structural analysis using Fourier transfer infrared spectroscopy indicated that P-O-P and Bi-O-P bonds..... More
