Reputation depends on quality,  quality comes from Hard!


Alumina Ceramics:

The anodized film is composed of two layers, and the porous thick outer layer is grown on a dense inner layer having dielectric properties, and the latter is called a barrier layer (also called an active layer). Observation by an electron microscope, The longitudinal and lateral faces of the film layer almost all have tubular holes perpendicular to the metal surface, which penetrate the outer layer of the film to form a barrier layer between the oxide film and the metal interface. The barrier layer is composed of anhydrous aluminum oxide, which is thin and dense and has high The hardness and the prevention of the passage of current. The thickness of the barrier layer is about 0.03-0.05μm, which is 0.5%-2.0% after the total film. The dense alumina is surrounded by the pores to form a honeycomb hexagonal body called a unit cell. The entire film layer is composed of a myriad of such unit cells. When the electrolyte is sulfuric acid, the sulfate content in the film layer is normally 13%-17%. The porous outer layer of the oxide film is mainly amorphous. Alumina and a small amount of hydrated alumina, in addition to the cation of the electrolyte. Most of the excellent properties of the oxide film are determined by the thickness and porosity of the porous outer layer, both of which are related to the anodizing conditions. closely related.
