The occurrence of anode effects is because as the electrolysis process, oxygen-ion electrolyte gradually reduced, when a certain degree, there is precipitation of fluorine and carbon generate carbon anode effects fluoride, carbon fluoride in the decomposition time and fine carbon particles deposited on the carbon particles attached to the surface of the anode, electrolyte and anode to prevent contact of the electrolyte cannot properly wet the anode, like water cannot wet oiled surface as the electrolyte - anode formed between a bad air film conductive layer, the anode overvoltage increases, causing anode effect. When adding a new alumina deposited on the anode and oxygen, the reaction of oxygen and carbon black, the anode surface gradually quiet, resistance is reduced, the electrolysis process and become normal.
After 40 years of research and development, electrolytic coloring to keep the depth and breadth of development, anodized aluminum is developed from the general protective - decorative purposes to the functional film special physical and chemical properties, from single colored salt to mixed salt coloring, from single uniform color to multi-colored, multi-color sense, and so on. Current porous alumina membranes toward functional direction research mainly from two aspects, one is the use of its porous structure, the development of new ultra-precision membrane; the other is through their nanoscale pores of various deposition the nature of different substances, such as metal-semiconductor, polymer materials, to prepare a new type of functional materials.
