Description

technical field [0001] The invention relates to the technical field of aluminum alloy film formation, in particular to an aluminum alloy electrolytic oxidation film formation device. Background technique [0002] In aluminum alloy anodic oxidation film formation technology, temperature control has always been the focus and difficulty of film formation quality. influences. In the actual oxidation process, many aluminum alloy anodic oxidation film formation methods have higher requirements on temperature, and it is necessary to perform oxidation film formation at a constant temperature or at a variety of different temperatures. [0003] However, the oxidation film-forming device in the prior art cannot accurately control the temperature, nor can it change the temperature during the film-forming process, so it cannot meet the requirements of aluminum alloy film-forming in many cases. Therefore, an oxidation film formation device capable of automatic temperature control is urg...
