Korean J. Met. Mater. 2024;62(3):180-189.   Published online 2024 Mar 5
DOI: https://doi.org/10.3365/KJMM.2024.62.3.180

Abstract
Capacitors not only store and release electricity but selectively conduct alternating current. Among the various types of capacitors, multi-layer ceramic capacitors (MLCCs) have been widely used in automotive, smartphone, and wearable devices because of their compact size and high capacitance capabilities. In this study, we have developed an electrolyte for..... More

                
Improving the Corrosion Resistance of AISI 316L Steel for Semiconductor Piping by Controlled Delta-Ferrite Content
Young Woo Seo, Chan Yang Kim, Bo Kyung Seo, Won Sub Chung
Korean J. Met. Mater. 2022;60(1):46-52.   Published online 2021 Dec 10
DOI: https://doi.org/10.3365/KJMM.2022.60.1.46

Abstract
This study evaluated changes in delta-ferrite content depending on the preheating of AISI 316L stainless steel. We also determined the reasons for the variation in delta-ferrite content, which affects corrosion resistance. Changes in delta-ferrite content after preheating was confirmed using a Feritscope, and the microstructure was analyzed using optical microscopy..... More

Electrochemical Corrosion Resistance and Electrical Conductivity of Three-Dimensionally Interconnected Graphene-Reinforced Cu Composites
Xue Li, Ateeq Ahmed, Byung-Sang Choi
Korean J. Met. Mater. 2021;59(11):821-828.   Published online 2021 Oct 28
DOI: https://doi.org/10.3365/KJMM.2021.59.11.821

Abstract
A three-dimensionally interconnected graphene-reinforced Cu (3Di Gr-Cu) composite was synthesized using a simple two-step process technique which involves the mechanical compaction of micronsized Cu particles followed by chemical vapor deposition (CVD) at 995 ℃. The microstructural properties of pure Cu and the 3Di Gr-Cu composite were investigated by optical..... More

Optimization of Electrochemical Variables of Pulse-Reverse Electroplating in Trivalent Chromium Bath to Enhance the Corrosion Resistance of Chromium Film
3가 크롬 도금욕에서 펄스 도금의 전기화학적 변수 최적화를 통한 크롬 도금막의 내식성 향상 연구
Chaewon Lim, Dongwook Lim, Bonil Ku, Sang Eun Shim, Sung-Hyeon Baeck
임채원, 임동욱, 구본일, 심상은, 백성현
Korean J. Met. Mater. 2019;57(10):641-647.   Published online 2019 Sep 6
DOI: https://doi.org/10.3365/KJMM.2019.57.10.641

Abstract
Electroplating chromium films in a trivalent chromium bath has been extensively investigated as a replacement for the conventional hexavalent chromium bath. However, commercialization of the trivalent chromium method has been hindered because the resulting chromium films exhibit inferior mechanical properties compared to hexavalent chromium coated film. In this study, we..... More
