Coating Method For Nano-structured Metallic Thin Films Using Supersonic Vacuum-Flow Deposition

摘要

The present invention relates to a process for the production of metal powders, comprising the steps of: injecting metal powders of 0.2 to 100 탆 diameter into a lamination chamber with a process gas having a temperature of 20 to 400 캜 and a pressure of 2 to 10 bar; And depositing the sprayed metal powder on at least one surface of a substrate selected from the group consisting of a metal steel plate, a ceramic and a plastic to form a metal coating layer, and a method of coating a metal thin film of a nanostructure through a supersonic vacuum flow lamination . According to the present invention, since the deposited metal particles form the crystal grains of the fine structure, the coating layer can be formed into a denser thin film and the mechanical characteristics can be improved.
