I would like to anodize a piece made from Aluminum alloy 7075-T6. I want to reach a thickness of a film around 15-19 micrometers. So far I chose these parameters: 10% H2SO4, 5°C, 25 V, 2 A/dm^2 . Are these parameters correct to reach this thickness?
Dear Dr. Weronika Sadurska ,

dear Weronika Sadurska ;
I advise you to use an acidic solution composed of 0.40M sulfuric acid, 0.53M of tartaric acid, and 0.25M sodium molybdate a Temperature of 20 °C and pH between 1 and 1,2. for a sample of 40mm width, 50mm long, and 5mm high the anodizing can be carried out under a potential difference of 14V immersed for about one minute. For more details can pass through the following references;
