Method suitable for continuously preparing high-temperature superconductive belt material

Abstract

The invention relates to a method suitable for continuously preparing a high-temperature superconductive belt material, which comprises the steps of: firstly, preparing a metal baseband; secondly, growing a compound separating layer on the metal baseband; then, growing a superconductive layer on the compound separating layer; and finally, growing a protecting layer on the superconductive layer. According to the invention, the in-situ preparation of the compound separating layer and the superconductive layer can be finished in the same coating system by adopting a multi-target multi-channel laser coating method; laser utilization rate and preparation speed of the belt material are greatly enhanced; vacuumizing time is reduced; equipment utilization rate is enhanced; and investment intensity of fixed assets is reduced so that the manufacturing cost of the high-temperature superconductive belt material is greatly reduced.

AI Technical Summary

Benefits of technology

The present technology uses multiple targets with different channels for creating high-quality coatings on strips quickly by applying specific types of energy onto them through an optical system that allows each target to be activated individually or simultaneously during operation. This results in improved efficiency and faster processing times while reducing costs compared to traditional methods like spray painting techniques.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the efficiency at producing rare earth element compounds called YBCO layers during mass production of thin films containing ceramics like tantaluminium nitride (TaN). Current techniques involve adding excessive amounts of magnetic powder into the molten liquid phase, resulting in increased costs associated with processing heavy elements. Additionally, existing methods require multiple steps involving heat treatment and cryogen cooling, leading to longer time required for their implementation within various markets including government agency systems, defense science facilities, transportation hub stations, etc., making them difficult to use in developing nations where fast response times may limit practicality.
