Publication number: 20250034692Abstract: An aluminum alloy-plated steel sheet having excellent workability and corrosion resistance and a method for manufacturing the same are disclosed. The aluminum alloy-plated steel sheet includes a base sheet, and an alloy-plated layer formed on the base sheet. Interfacial roughness between the alloy-plated layer and the base steel sheet is 25 ?m or less. Such an aluminum alloy-plated steel sheet prevents microcracks generated during hot forming and has excellent seizure resistance and corrosion resistance. A method for manufacturing such an aluminum alloy-plated steel is also disclosed.Type: ApplicationFiled: October 17, 2024Publication date: January 30, 2025Applicant: POSCO Co., Ltd.Inventors: Suk-Kyu Lee, Hyeon-Seok Hwang, Myung-Soo Kim, Jong-Gi Oh, Kwang-Tai Min

Patent number: 9190239Abstract: Disclosed is an apparatus and method for low-temperature plasma immersion processing of a variety of workpieces using accelerated ions, wherein low-temperature plasma is distributed around a cylindrical workpiece placed in a chamber, the workpiece is enclosed with a housing including a multi-slot extracting electrode to isolate the workpiece from plasma, and a negative potential sufficient to induce sputtering is applied to the workpiece and the electrode, so that ions from plasma are accelerated within the sheath formed between the extracting electrode and plasma, pass through the slot part of the electrode and bombard the workpiece, thus polishing the surface of the workpiece. This apparatus and method is effective for surface smoothing to ones of nm of large cylindrical substrates particularly substrates for micro or nanopattern transfer.Type: GrantFiled: October 27, 2010Date of Patent: November 17, 2015Assignee: Korea Electrotechnology Research InstituteInventors: Sung Il Chung, Hyeon Seok Oh, S. A. Nikiforov, Pan Kyeom Kim, Hyeon Taeg Kim, Jeong Woo Jeon, Jong Moon Kim

Patent number: 7298452Abstract: A flexible substrate, which has a photosensitive agent applied thereon, is continuously supplied from a supply unit to a guide unit where light is irradiated from a light source on a section of the substrate. A mask is positioned between the substrate and the light source so that the light from the light source selectively subjects the section of the substrate to exposure. Hence, it is possible to form a pattern having a continuous slanted structure for a large-area display panel.Type: GrantFiled: November 19, 2004Date of Patent: November 20, 2007Assignees: LG Electronics Inc., Korea Electronics Technology InstituteInventors: Suk-Ho Park, Young-Jun Choi, Hyeon-Seok Oh, Jae-Ha Lim, Suk-Won Jung
