전기장 시뮬레이션을 이용한 대면적 알루미늄 양극산화 공정

초록

This paper presents an aluminum anodic oxidation process after simulation of the electric field. Electric field simulation of the anodizing process was performed by the Ansys “MAXWELL” program. Electric field simulations of aluminum anodic oxidation were performed for a total of 12 models. When a current distribution grid layer was not used, the average current density deviation on the aluminum plate was 50.10 A/cm2, and the average current density deviation of the actual experimental model with the current distribution grid layer was 0.008 A/cm2. As a result, the current density deviation formed on the aluminum plate was reduced by a factor of 6,250 by using the current distribution grid layer. Based on the aluminum anodic oxidation experiment, the average thickness of the alumina layer was 563 nm ± 65 nm in the region where the current density value was uniform in the simulation.
