Abstract

A rare-earth-doped alloy oxide luminescent coating and a preparation method thereof relate to the field of material engineering. An interdiffused oxide metallurgical layer is formed between the coating elements and the substrate elements of the luminescent coating, forming a gap between the coating and the substrate. There is no obvious interface effect, and the content of each element in the metallurgical layer is distributed in a gradient from the surface to the matrix. The preparation method of the rare earth-doped alloy oxide luminescent coating is divided into three stages: a pretreatment stage; an alloy and rare earth co-infiltration treatment stage; and a plasma oxidation treatment stage. The present invention uses the co-infiltration of rare earths and metals in an oxygen environment to prepare a rare earth doped alloy oxide coating with luminescent properties on the metal surface where the contents of rare earth oxides and matrix oxides are respectively distributed in gradients, so that the coating and The combination between the substrates is firm, so the invention can greatly improve production efficiency, reduce investment, reduce production cost, and can achieve better economic benefits.

Description

technical field [0001] The invention belongs to the field of material engineering, and in particular relates to a luminescent coating of alloy oxide doped with rare earth elements and a preparation method of the luminescent coating. Background technique [0002] At present, the luminescent materials prepared with oxide as the matrix mainly adopt liquid co-deposition method, sol-gel method, magnetron sputtering and other methods. People have successfully realized the doping modification of transition metal yttrium in the ordered mesoporous zirconia framework by using surfactant-assisted template and post-treatment process. The patent (CN200310117750.9) discloses a method of rapidly heat-treating sol-gel on different substrates to prepare an oxide film, by preparing a sol precursor, spin coating coating, rapid heat treatment, film formation, and cyclic operation. The preparation method of this method is The advantage is that the film components are uniform and controllable, t...
