The method of eliminating bubbles on the surface of anodized workpieces

　　The method to eliminate the bubbles on the surface of anodized workpieces is to fix the workpiece with a fixture, and place the fixture and the workpiece in the oxidation tank obliquely, so that the fixture and the horizontal surface form an included angle of 10 ° to 80 ° and ensure that the bottom end of the workpiece is in contact with the bottom end point of the workpiece。

The method to eliminate the bubbles on the surface of anodized workpieces is to fix the workpiece with a fixture, and place the fixture and the workpiece in the oxidation tank obliquely, so that the fixture and the horizontal surface form an included angle of 10 ° to 80 ° and ensure that the bottom end of the workpiece is in contact with the bottom end point of the workpiece During anodizing, the fixture drives the workpiece to make a uniform inclined circular movement in the groove, that is, the workpiece makes a uniform horizontal circular motion in the groove, and the moving speed of the workpiece is 10 mm / s-150 mm / s. After the anodizing, the movement of the fixture and the workpiece is stopped, and the fixture and workpiece are removed and cleaned.

On the one hand, the higher oxidation voltage caused by bubbles is reduced, that is to say, the oxidation energy consumption is reduced. On the other hand, the heat transfer time of bubbles to the plating solution is reduced, and the bath temperature is increased.

This method uses the friction force between the workpiece and the plating bath and the centrifugal force of the workpiece's circular motion to separate the bubbles from the workpiece surface and eliminate the bubbles on the workpiece surface. This method not only improves the film quality, but also reduces the oxidation and cooling energy consumption, and solves the technical problem of uneven film thickness and performance caused by bubbles on the surface of anodized workpiece.
