At this time, under the applied voltage, the partially damaged oxide film can be repaired and restored through the action of the catholyte(white aluminium oxide). The second purpose is to prefabricate a certain required special oxide film with a certain thickness on the surface of the aluminum box(garnet abrasive). For example, a porous oxide film is formed in advance, and then a dielectric film is formed between the porous film and the aluminum.

The self-healing effect of the anodic oxide film of the electrolytic capacitor is closely related to the catholyte, so the highest forming voltage is limited(black aluminum oxide), and the breakdown voltage of various valve gold isolation oxide films The order of high and low is: the typical process flow is pre (pre-)treatment→first-stage formation(garnet suppliers), first-stage formation→third-stage formation-depolarization-post-treatment-washing-drying-receiving.(cheap pink fused alumina f grade suppliers colombia)

In other words(brown fused alumina price), it is controlled by the local breakdown of the oxide film dielectric, so that the upper limit of the working voltage of the aluminum electrolytic capacitor is also limited. The level of flash fire voltage is closely related to the nature of the anode metal, the impurities contained on the surface, damage, etc.(black oxide aluminum), and it is also related to the concentration of the electrolyte, the type of ions and the temperature of the liquid.

(cheap pink fused alumina f grade suppliers colombia)The porous oxide waist plays a protective role(white fused alumina), so that the dielectric film generated in the subsequent forming process is less subject to mechanical damage and CI erosion, and achieves the role of stabilizing the film layer, so that the capacitor has good electrical and temperature resistance characteristics(150 grit aluminum oxide). This needs to be removed, so the corrosion box needs to be washed and dried before forming.

When a voltage is applied to the capacitor(silicon carbide price), the damaged area of the anodic oxide film is provided by the electrolyte to provide oxygen ions and the metal ions (AIP+) there to form an oxide film again. The formation mechanism is that the anion OH or O passes through the porous membrane and the thin barrier layer in the middle(silicon carbide companies), and reaches the metal surface to generate the barrier layer oxide film.(cheap pink fused alumina f grade suppliers colombia)

The advantages of heat-treated oxide film are high formation efficiency and power saving(white corundum). There are three methods, which can be selected according to the characteristics of different forming tanks, which are briefly described below: metal aluminum is subjected to high temperature heat treatment in the atmosphere(arc fused alumina). Obviously, the oxygen in the air will combine with aluminum to promote the formation of surface oxide film.

(cheap pink fused alumina f grade suppliers colombia)If the heat treatment temperature exceeds 450C, the growth of the film is accelerated, and the grown film contains a crystalline oxide film(white aluminum oxide). The locally damaged oxide film grows rapidly. This oxidation formed by heat treatment The film is then anodized in the forming solution(glass beads supplier). Because the amorphous film becomes a crystalline film, the density increases, which means that the volume shrinks and causes cracks.

Generally thickening repair and recovery(green carborundum), there is another situation in the repair process of oxide film, that is, if there are impurity ions or other defects on the surface of oxide film, it can not be repaired and thickened. But there are also disadvantages: under extremely low voltage, the capacitor loss is large; when there is no load at high temperature(brown fused aluminum oxide manufacturers), the leakage current increases; the oxide film is prone to cracking.(cheap pink fused alumina f grade suppliers colombia)
