Korean J. Met. Mater. 2017;55(5):296-307. Published online 2017 May 9
DOI: https://doi.org/10.3365/KJMM.2017.55.5.296

Abstract
Magnesium alloys, which possess excellent specific strength and castability, are highly susceptible to corrosion. Although anodizing is widely used to resolve this problem, it requires toxic electrolytes and produces relatively thin and weak surface coatings. Recently, plasma electrolytic oxidation (PEO) has emerged as an alternative to anodizing. Although it is... More

Korean J. Met. Mater. 2016;54(10):723-731. Published online 2016 Oct 5
DOI: https://doi.org/10.3365/KJMM.2016.54.10.723

Abstract
The effect of a small amount of added Mg on the microstructure, Fe-Al inhibition layer, corrosion resistance and welding properties of hot-dip galvanized and galvannealed steel sheets were investigated. Both the microstructure and distribution of Mg were measured by scanning electron microscopy, transmission electron microscopy, glow discharge spectrometer and electron..... More

Korean J. Met. Mater. 2016;54(8):552-558. Published online 2016 Aug 5
DOI: https://doi.org/10.3365/KJMM.2016.54.8.552

Abstract
Vacuum kinetic spraying (VKS) is a relatively advanced process, by which a dense film can be fabricated at room temperature. Various materials including ceramic, metal, polymer and composite can be used as the substrate and coating materials. In this research, red and blue color films were successfully fabricated on glass..... More
