Abstract

The invention provides a preparation method of a fullerene / metal composite film on a metal surface. The preparation method is characterized by comprising the following steps of: (1) surface pretreatment of a substrate material: cleaning, acid-cleaning and activating a metal surface; (2) preparation of an electrophoresis solution, dispersing fullerene in tetrahydrofuran, ultrasonically oscillating, filtering, reducing and regulating PH value to be 8-12; (3) preparation of a fullerene film on the metal surface with an electrophoresis method; (4) preparation of electroplating liquid: preparing the electroplating liquid containing Ni, Sn, Zn, Cu, Cr, and the like; (5) preparation of a fullerene / metal compositecoating on a metal plate, which is provided with the fullerene film and obtained from the step (3), by adopting an electroplating method; and (6) heating. The method provided by the invention can be used for modifying the metal surface; and particularly a novel surface coating film metal material can be derived and a brand-new nano composite plating metal product can be developed by utilizing the thermal diffusion characteristic of the fullerene material.

Description

technical field [0001] The invention relates to the field of nanotechnology, in particular to a method for plating a composite film of fullerene / metal material on the surface of a metal substrate. Background technique [0002] Composite coating is a special coating formed by uniformly mixing one or more insoluble solid particles into the metal coating. The techniques for preparing composite coatings generally include electrodeposition, surfacing, thermal spraying, and cold spraying. Among them, electrodeposition, that is, composite plating, is more commonly used. This technology has developed rapidly in recent years and has been widely used in the field of engineering technology. Adding nanomaterials to the metal coating has evolved into a nanocomposite plating technology. Due to the unique properties of nanomaterials such as scale effect, surface effect, quantum size effect and quantum tunneling effect, adding nanomaterials to the coating will benefit Improve the strength...
