Abstract

The invention discloses a composite multi-layer hydrophobic and anti-corrosion film as well as a preparation method and an application thereof. The film comprises a first metal adhesion layer, a hydrogen-containing amorphous carbon film layer and a hydrogen-free amorphous carbon film layer from bottom to top and is prepared through magnetron sputtering with control on the ratio of argon to hydrogen. Physical and chemical characteristics of different hybridization composition types of carbon are considered, the amorphous carbon film adopting the dual-layer structure is designed, the a-C:H filmis used as a conductive substrate, and thin-layer a-C with the surface covered is used as the anti-corrosion and hydrophobic medium. Through the structural design, the amorphous carbon film can effectively improve the anti-corrosion performance of the film structure on the basis that the conductivity is guaranteed. The design concept has the great prospect for application in the field of metal corrosion resistance and bipolar plates and has the very positive promotion significance for application of metal bipolar plates to hydrogen cells.

Description

technical field [0001] The invention relates to the field of metal corrosion resistance, in particular to a composite multilayer hydrophobic corrosion resistance film and its preparation method and application. Background technique [0002] Amorphous carbon is a general term for a large class of amorphous carbon. Its structure is mainly composed of sp2 hybridization (graphite-like structure) and sp3 hybridization (diamond-like structure) atomic carbon, and the sp3 hybridization carbon film can effectively prevent corrosion. The erosion of ions consolidates the mechanical properties and has good hydrophobic properties, but the conductivity of the carbon film of this composition is poor; while the result of sp2 hybridization mainly affects the conductivity of the amorphous carbon film, but the hydrophobic effect is poor. In some corrosion-resistant structures, especially in hydrogen fuel cells, the metal bipolar plate, one of its core components, often requires an amorphous ca...
