The methods employed were hard sulfuric acid (high hardness), soft sulfuric acid (low hardness), boric-sulfuric mixed acid, tin-sulfuric mixed acid, and chromic acid solutions. Each process was completed under optimized conditions. The surface morphology was observed using field emission scanning electron microscopy (FE-SEM) and a digital camera. For the determination of thermal performance, Fourier transform infrared spectroscopy (FT-IR) was used to measure the emissivity at 50 \u00b0C, and laser flash analysis (LFA) was utilized to analyze the thermal diffusivity at room temperature to 300 \u00b0C. The radiative property of metals is often ignored because of their low emissivity, however, in this research, the emissivity of the metal oxides was found to be higher than that of bare metal series. This study improved the heat dissipation properties by oxidization of Al via the anodizing process.<\/jats:p>","DOI":"10.3390\/sym13030433","type":"journal-article","created":{"date-parts":[[2021,3,8]],"date-time":"2021-03-08T04:01:25Z","timestamp":1615176085000},"page":"433","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Effects of Anodizing Conditions on Thermal Properties of Al 20XX Alloys for Aircraft"],"prefix":"10.3390","volume":"13","author":[{"given":"Junghyun","family":"Park","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Pusan National University, Busan 46241, Korea"},{"name":"Korea Institute of Ceramic Engineering and Technology, Gyeongsangnam-dom, Jinju 52851, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyeongsik","family":"Son","sequence":"additional","affiliation":[{"name":"Korea Institute of Ceramic Engineering and Technology, Gyeongsangnam-dom, Jinju 52851, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7740-1633","authenticated-orcid":false,"given":"Junghoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Metallurgical Engineering, Pukyong National University, Busan 48513, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2826-7359","authenticated-orcid":false,"given":"Donghyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Korea Institute of Ceramic Engineering and Technology, Gyeongsangnam-dom, Jinju 52851, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wonsub","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Pusan National University, Busan 46241, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Markopoulos, A.P., Papazoglou, E.L., and Karmiris-Obrata\u0144ski, P.
