Korean J. Met. Mater. 2019;57(5):316-323.   Published online 2019 Apr 10
DOI: https://doi.org/10.3365/KJMM.2019.57.5.316

We demonstrated an effective method for fabricating a highly efficient flexible transparent electrode in an oxide/metal/oxide configuration based on an ultrathin Cu film. It exhibited low losses in optical transmittance and electrical conductivity while minimizing current loss due to pinhole-related leakages. The Cu film was developed on a chemically heterogeneous..... More

Korean J. Met. Mater. 2018;56(4):289-295.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.289

Oxi-nitrocarburizing treatment was performed to improve the anti-corrosion and anti-wear properties of low carbon steels. The oxi-nitrocarburizing was carried out in 2 steps: a gas nitrocarburizing step at 560 ℃ and an oxidation step at 550 ℃ for 30 min with steamed water. The mechanical and chemical properties of the..... More

624 Wetting Behavior of Liquids on Micro-Patterned Polymer Surfaces Fabricated by Thermal Imprinting
Kwang-Jin Bae, Wenhui Yao, Yiliang He, Young-Rae Cho
Korean J. Met. Mater. 2017;55(9):624-631.   Published online 2017 Aug 30
DOI: https://doi.org/10.3365/KJMM.2017.55.9.624

The wetting behavior of liquids on solid surfaces is important in the study of surfaces and interfaces. In this study, the wetting behavior of deionized (DI) water and hexadecane on fluorinated and micro-patterned polymer surfaces was investigated. The sample surfaces were processed by spray coating and thermal imprinting, respectively. The..... More

523 Thermal Conductivity of Double-Layer Clad Metals along the Thickness Direction Using Light Flash Analysis and Estimation Models
2층금속 클래드메탈의 두께방향으로 섬광법 적용 열전도도 측정과 예측모델 연구

Korean J. Met. Mater. 2017;55(7):523-528.   Published online 2017 Jul 4
DOI: https://doi.org/10.3365/KJMM.2017.55.7.523

Heat transfer plays a critical role in the fabrication of high efficiency electronic devices. Double-layer clad metals consisting of stainless steel (STS) and aluminum (Al) alloy were fabricated by the roll bonding process, and their thermal conductivity was calculated using measurements of density, specific heat, and thermal diffusivity obtained by.....

Korean J. Met. Mater. 2017;55(6):446-452.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.446

The thermal properties of two-layered materials composed of a polymer layer embedded with dielectric AlN particles (AlN composite) coated on top of an aluminum (Al) substrate were investigated by light flash analysis (LFA). The thermal conductivity of the specimens was measured as a function of the AlN composite volume fraction..... More
