Yong Min Jeon, Si Hong Ryu, Min Jun Kim, Seong Eui Lee
전용민, 유시홍, 김민준, 이성의
Korean J. Met. Mater. 2023;61(12):909-914.   Published online 2023 Nov 30
DOI: https://doi.org/10.3365/KJMM.2023.61.12.909

Abstract
In this study, a composition-gradient thin film was applied for the formation of intermediate layer of Ti seed layer for an stable electrode stack Ag metal layer. Various composition of Ag-Ti hetero metal layer were simultaneously deposited by using the sputtering process with Ti and Ag target, respectively. An intermediate..... More

Korean J. Met. Mater. 2022;60(4):301-306.   Published online 2022 Mar 28
DOI: https://doi.org/10.3365/KJMM.2022.60.4.301

Abstract
Currently, the need for high performance heaters for industrial application is increasing, and repeated wear, rapid temperature change, and uneven temperature can cause deteriorating quality and reduced productivity. The ceramic heater in this study consists of a substrate, an electrode layer, and a protective layer, and low-melting temperature glass frit..... More

                
A Study on Sebum Hardening Effect of ZnO Powder
Sebum경화 기능형 ZnO powder 특성 연구
Yong Min Jeon, Jin Gu Kwon, Si Hong Ryu, Yeong Cheol Lee, Seong Eui Lee
전용민, 권진구, 유시홍, 이영철, 이성의
Korean J. Met. Mater. 2021;59(3):195-200.   Published online 2021 Feb 19
DOI: https://doi.org/10.3365/KJMM.2021.59.3.195

Abstract
Zinc oxide is transparent inorganic UV absorber and widely used as a sunscreen. But sunscreen on the skin is easily erased by sebum, so zinc oxide with a sebum curing function was studied. In this study, a zinc oxide powder was prepared using zinc chloride and sodium hydroxide via a..... More
