Abstract

The invention discloses an electrode distance adjustable type microarc oxidation electrode holder, which is characterized by consisting of three transverse parallel rectangular support frames, two long screw rods which are perpendicular to and connected in series with the rectangular support frames, and adjusting nuts on the long screw rods. By adopting the electrode distance adjustable type micro-arc oxidation electrode holder, the electrode distance can be changed to control the distribution of oxidation voltage during the microarc oxidation process, so that energy consumption is controlled, a required cathode can be replaced in any time to enlarge the distance range which can be adjusted by the electrode, current efficiency is improved, and thus the electrode distance adjustable type microarc oxidation electrode holder is simple and easy, and practical.

Description

technical field [0001] The invention relates to a device used in a material surface micro-arc oxidation treatment process, in particular to an adjustable electrode distance micro-arc oxidation electrode fixture. Background technique [0002] In the process of micro-arc oxidation treatment, the relationship between the position of cathode and anode in the electrolytic cell is an important issue to be considered. Many studies have shown that reducing the electrode distance can reduce the energy loss of the solution under the premise of ensuring that the micro-arc oxidation discharge does not occur short circuit. The voltage between the electrodes (approximate to the oxidation voltage) can be roughly divided into the solution pressure drop and the membrane layer pressure drop. When the electrode distance decreases, the oxidation voltage becomes smaller, while the membrane layer pressure drop is approximately unchanged, so the solution pressure drop decreases significantly a...
