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
Abstract
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.....

Study of Solution-Processed Indium Zinc Oxide TFTs Made by Simultaneous Spin Coating and Ultraviolet Light Irradiation
스핀코팅과 자외선 조사의 동시 적용을 기반한 용액 공정형 Indium Zinc 산화물 트랜지스터 연구

Korean J. Met. Mater.
2017;55(8):572-575. Published online 2017 Aug 1
DOI:
https://doi.org/10.3365/KJMM.2017.55.8.572
Abstract
We investigated solution-processed indium zinc oxide (IZO) thin-film transistors (TFTs) which were fabricated by spin coating with simultaneous irradiation by ultraviolet light. The proposed treatment enhanced the efficient condensation and densification of the oxide semiconducting channel layer by decreasing oxygen-vacancy-related defects and increasing metal-oxide bonds. An IZO TFT irradiated for.....

Calculation of Inductance, Capacitance, and Microwave Absorbance of Modified Square Loop Frequency Selective Surface
변형된 사각 루프 주파수 선택 표면의 인덕턴스, 커패시턴스 계산 및 전파흡수특성
Tian Liu, Sung-Soo Kim류전, 김성수
Korean J. Met. Mater.
2017;55(6):412-418. Published online 2017 Jun 1
DOI:
https://doi.org/10.3365/KJMM.2017.55.6.412
Abstract
The square loop (SL) is the typical pattern of a frequency selective surface (FSS) with high inductance (L) and capacitance (C). In this study, modified patterns including split square loop FSS (SSL-FSS) and I-type FSS (I-FSS) are proposed, and their L and C values were estimated using the equivalent circuit.....

Abstract
The effects of particle size on the surface properties of HVOF spray coating were studied to improve of the durability of metal components. Micro and nano sized WC-12Co powders were coated on the surface of Inconel718, and the effects of particle size on surface properties were studied. Surface hardness was.....

The Effect of Mixed Slurry of Fe and Graphite on the Characteristics of Laser Carburized Surface
레이저 침탄공정시 철과 흑연의 혼합 슬러리가 침탄특성에 미치는 효과
Won-Jong Ji, Seong-Hoon Lee, Young-Hoon Moon지원종, 이성훈, 문영훈
Korean J. Met. Mater.
2017;55(1):16-23. Published online 2017 Jan 5
DOI:
https://doi.org/10.3365/KJMM.2017.55.1.16
Abstract
Laser surface carburizing can be achieved by a laser alloying mechanism, which includes melting the graphite coated substrate and dissolution of the graphite in the liquid state. The drawback of laser carburizing is that process-induced cracks frequently form on the carburized surface as a result of carbon enrichment and the.....
