Title:
HIGH-ENTROPY METAL OXIDE COATING, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/115929
Kind Code:
A1
Abstract:
The present invention relates to the technical field of coatings and provides a high-entropy metal oxide coating, a preparation method therefor and a use thereof. The method comprises: first preparing a metal salt solution, preheating a substrate to 300-500℃, oxidizing the metal salt solution by means of a spray gun by using a plasma spraying technology, and depositing the metal salt solution on a surface of the substrate to obtain a high-entropy metal oxide coating; the concentration of each metal salt in the metal salt solution is 0.1-0.4 mol/L, the feeding flow rate of the metal salt solution is 5-50 mL/min; the spray gun is provided to have a power of 28-40 kW, a current of 790-850 A, a voltage of 38-44 V, a spraying distance of 50-200 mm, a flame core temperature of 10000-15000 K, and a moving speed of 100-1000 mm/s; and the spraying cycle is 2-50 times. According to the high-entropy metal oxide coating in the present invention, the preparation process can be simplified, the stability of the electrode coating can be improved, and preparation of the high-entropy metal oxide electrode coating oriented to practical engineering application can be better achieved.
