Hard anodic oxidation, and what is the difference between ordinary anodic oxidation process conditions, although the difference is not very big, is to use principle of electrolytic cell used to machining, but processing conditions is very big difference, meaningless from current, temperature, and the proportion of electrolyte ways, there are bigger difference.So what's the difference between hard anodizing and ordinary anodic oxidation?
One, from the thickness of the oxide film.Hard anodic oxidation because the lower the temperature of the processing, the thicker the thickness, if the thickness is not the corresponding effect.So the thickness is much thicker than ordinary anodized, usually 6 to 20 times the normal oxide film.
2. From the touch of the oxide film.Because the product is to be applied to our life, so the feeling is also to consider the question.Hard anodic oxidation and ordinary anodic oxidation generated oxide film can be touched, just ordinary anodized oxide film is smooth, smooth, and hard anodic oxidation of oxide film is uneven.
3. From the place of use.Products that have been oxidized by hard anodes are generally used in places where high strength performance is required, because it is very anti-corrosive, anti-friction, non-conductive and so on.And the product that passes ordinary anodic oxidation, commonly is used in the place that can see and touch commonly in ordinary times, it is to serve for ordinary people mainly, have certain beautiful effect.Plus ordinary oxidation can be processed again, with the oxidation process, according to people's needs of different colors.
