The aim of the article is to evaluate the influence of the parameters of time and type of electrolyte on the thickness and hardness of the film generated by anodic oxidation on the aluminum alloy AA5083-H116. Electrolytes were evaluated, oxalic and phosphoric type with times of 30 and 45 min of anodizing. The morphology of the films was observed by scanning electron microscopy (SEM). The hardness of the surfaces was evaluated by means of Vickers tests. To validate the results, a factorial design was applied 22 . The results showed that the oxalic type electrolyte has the highest values of thickness and hardness.
