Title:
METHOD FOR PREPARING CR-AL-C BASED MAX PHASE COATING AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/259046
Kind Code:
A1
Abstract:
Disclosed are a method for preparing a Cr-Al-C based MAX phase coating and the use thereof. The method includes firstly depositing a Cr-C layer onto the surface of a substrate through deposition by means of electric arc ion plating, wherein the thickness of the Cr-C layer is 0.5-5 μm; then depositing an Al layer onto the surface of the Cr-C layer through deposition by means of magnetron sputtering to obtain an Al/Cr-C coating; and finally, performing a heat treatment to obtain the Cr-Al-C based MAX phase coating with a (103) crystal face being preferentially oriented. The coating has a good electrical conductivity and corrosion resistance. Compared with the prior art, the Cr-Al-C based MAX phase coating prepared by the method not only improves the interface electrical conductivity between the coating and the substrate, but also improves the corrosion resistance, and has an excellent electrical conductivity, corrosion resistance and protection performance in severe environments.
