The paper presents the design of a test bench to perform electrochemical process of anodizing on an aluminum piece. The objective is to analyze the influence of the electrolytic solution, temperature and current in the anodic layer formation. The temperature and current controllers are implemented in an open hardware Arduino technology, which guaranteeing the stability of these variables in the process. A mechanical agitator was also added to maintain the homogeneous solution in the tests. An user interface is designed in LabView, where the variables are monitored in real time and allow the storage of the historical data for later analysis.
