Title:
SUBSTRATE ETCHING METHOD FOR TITANIUM-BASED DIMENSION STABILIZATION TYPE ANODE
Document Type and Number:
WIPO Patent Application WO/2021/017104
Kind Code:
A1
Abstract:
The present invention provides a substrate etching method for a titanium-based dimension stabilization type anode. In the etching process, optimization on the titanium substrate surface micro morphology is achieved by using a nitrogen introduction method. The effect of enhancing the bonding force of a substrate and a coating is achieved by improving the surface roughness of the substrate, and therefore the purposes of effectively prolonging the working life of the titanium-based dimension stabilization type anode and improving the working efficiency of electrodes to a certain extent are achieved. Compared with a conventional titanium substrate, the method can achieve the purposes of saving electrodeposition energy consumption, reducing electrode damage and reducing the replacement cost, and satisfies the industrial application demands for less electrode preparation processes and low cost.
