DOI: https://doi.org/10.3365/KJMM.2020.58.8.507

In this study, we tried to improve the oxidation resistance of Nb-12Si (wt%) alloys at 1200 °C or higher through pack cementation coatings. Nb-12Si (wt%) alloys were prepared by arc-melting under Ar atmosphere. When the alloys were coated using pack powder mixtures composed of Si, Al2O3 and NaF, two silicide..... More

Korean J. Met. Mater. 2020;58(3):201-206.   Published online 2020 Feb 3
DOI: https://doi.org/10.3365/KJMM.2020.58.3.201

Anti-reflective (AR) coatings are popular because they offer high durability with effective reflectance and glare reduction, and they can endure both physical and environmental damage. Magnesium fluoride (MgF2) has been used as a nanoparticle coating on AR coating materials by many researchers because they exhibit high transmittance and antireflection characteristics..... More

Korean J. Met. Mater. 2019;57(3):131-137.   Published online 2019 Feb 8
DOI: https://doi.org/10.3365/KJMM.2019.57.3.131

Alloys containing the β/B2 phases of Ti-45Al-3Mo, Ti-45Al-3Mo-2Nb and Ti-45Al-5Mo were prepared using an vacuum arc-melting machine. Heat-treatments were carried out at 1250 oC in an Ar atmosphere. The temperature of 1250 oC is the temperature region of phase α + γ + (β/B2), and the heat treatment condition which..... More

Factors Influencing Plasma Electrolytic Oxidation(PEO) Coatings on Magnesium Alloys: A Review
마그네슘 합금의 플라스마전해산화 코팅에 영향을 미치는 제반 요소들에 대한 고찰
Gunchoo Shim
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
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

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
