Problems solved by technology

The advantage of the pre-mixing method is that the preparation process is relatively simple, but since the mixing process is usually liquid phase mixing, it is difficult to avoid the problem of fiber agglomeration during the mixing process, which often leads to the generation of pores in the coating, causing cracking of the coating
[0005] Compared with the pre-mixing method, the in-situ composite method can well achieve the uniform dispersion of fibers in the substrate, but its preparation process is more complicated, often inseparable from advanced surface engineering technology (physical vapor deposition or chemical vapor deposition)

Abstract

The invention provides an in-situ preparation method of a metal fiber reinforced composite film. Metal fibers (silver, copper, aluminum, tin, platinum and the like) are generated while the thin film is formed through sputtering by means of a plasma assisted chemical vapor deposition method and the catalytic action of carbon plasmas, thereby achieving in-situ preparation of the metal fiber reinforced composite film. The method realizes one-dimensional metal fiber sputtering synthesis and in-situ preparation of the fiber reinforced composite film. The composite structure can adjust the stress state in the thin film and the film toughness, and simultaneously endows the film with excellent electrical conductivity, abrasion reduction performance and the like.

Description

technical field [0001] The invention belongs to the technical field of composite coating preparation, and in particular relates to an in-situ preparation method of a metal fiber reinforced composite film. Background technique [0002] Thin film material science is an important branch of material science. By depositing and adhering a layer of film different from the substrate material on the surface of the substrate, the substrate is endowed with excellent wear resistance, corrosion resistance and surface mechanical properties, and even the parts obtain special thermal and electrical properties. , light, sound, magnetic and other properties. Composite thin film is an important direction of thin film research, which aims to improve the performance of a single thin film or obtain performance that cannot be achieved by a single thin film through composite technology. According to the structure, the composite film can be divided into nanocrystal embedded composite film, nano mul...
