초록

Physical properties of Plasma electrolytic oxidized 8 different kinds of Al alloys, A-1100, A-2024, A-5052, A-6061, A-6063, A-7075, ACD-7B and ACD-12 were investigated. The electrolyte for PEO was Na2SiO3 and NaOH and some alkali earthen metal salts system solution. η-alumina, as well as γ-alumina, was main crystal phase, which were ever reported. Also, Al4.95Si1.05O9.52 was found only in this research. So we can conclude that the process conditions of PEO apparatus and composition and concentration of its electrolyte affects crystal structure and physical properties of PEO layers much more than the compositions of Al alloy.
