Optimization of Micro-Arc Oxidation Electrode Structure by Finite Element Analysis

Abstract:

In order to realize the application of finite element analysis in structural optimization of micro-arc oxidation electrode, effects of two kinds of electrode mode (one and two cathodes) on thickness and surface morphology of ceramic coatings prepared by micro-arc oxidation on aluminum alloy were researched by experiment. Meanwhile, Ansoft Maxwell finite element software was used to analysis the main influence factor (electric field intensity). We contrasted the analysis conclusion above with the forecast results in experiment. Effect of electric field intensity on thickness and surface morphology of ceramic coatings were explained from micro level, the correctness of the finite element analysis software was verified. The results show that three electrodes mode is better than two electrodes mode, the former can not only make the thickness of ceramic coatings thicker, but also make sure the size and quantity of discharge channel bigger and more, and growth power enough.
