An electrode protection submerged micro-arc oxidation fixture

Abstract

The invention discloses an electrode protection submerged micro-arc oxidation clamp, which is composed of a conductive electrode 1, an acid and alkali resistant sealing rubber ring 2, an elastic structure PVC plate 3, a PVC pipe 4, a conductive wire 5, a clip spring 6, and a PVC splint 7. The PVC pipe contains protruding hook grooves and is hooked with the elastic structure PVC board; the conductive electrode is fixed on the elastic structure PVC board and is connected with the wire; the wire is drawn from the hollow PVC pipe and connected to the micro-arc oxidation anode electrode ; There are gaps on both edges of the PVC splint, so that the clamp can be fixed in the micro-arc oxidation tank; the clamp spring is used for the opening and closing of the clamp. The invention has the advantages of simple structure and low manufacturing cost, and has the advantages of detachment, multi-clamp coordination, customization, etc. It is suitable for the micro-arc oxidation processing of various types of acid-base electrolytes and most flat workpieces at present, and has extremely high performance. Large application and market prospects.

Description

technical field [0001] The invention relates to an electrode protection submerged micro-arc oxidation fixture, which is suitable for the relevant research and production of micro-arc oxidation of titanium, magnesium, aluminum and related alloy workpieces which can be micro-arc oxidation. Background technique [0002] Micro-arc oxidation (MAO) technology is an emerging surface treatment technology developed from traditional anodizing technology. Non-ferrous metals such as aluminum, magnesium, titanium, zirconium and their alloys are placed in a special electrolyte, and a high voltage or current is applied to make a layer of hard ceramics or other functional oxides grown on the surface of the base metal in situ. At the same time, the bonding strength between the film layer and the substrate is high, it is not easy to crack and fall off, and it has excellent corrosion resistance, wear resistance, and insulation. [0003] In the process of micro-arc oxidation, traditional clamp...

AI Technical Summary

Problems solved by technology

[0003] In the process of micro-arc oxidation, the traditional fixture is usually used to clamp the workpiece. The existing problem is that the fixture cannot contact the electrolyte. Oxidation will have a negative impact on the entire experiment, and the fixture and electrode need to be processed and cleaned afterwards, which will greatly reduce the service life of the fixture and electrode

However, the lack of contact of the gripper with the electrolyte would result in a solution-air interface on the gripped workpiece, which would have an undesirable effect on MAO
