Problems solved by technology

[0003] Prior art methods regulate its surface chemical composition on the basis of metal surface microscopic topography or build its surface topography on the basis of a certain surface chemical composition or use both methods simultaneously; but the construction method of metal surface microscopic topography is relatively Complex, difficult to achieve effective control of metal surface micro-morphology
In addition, with the change of the microscopic morphology of the metal surface, it is not easy to control the chemical composition of the surface.

Abstract

The invention provides a preparation method for preparing a bionic intelligent metal material surface through 3D printing. The method comprises the following steps of: S1, preparing metal surfaces with different micro-morphologies by a 3D metal laser sintering technology; and S2, the metal surfaces with different micro-morphologies are processed by a surface chemical reaction treatment technologyto obtain the metal functional surfaces with different surface chemical compositions and surface roughness. The metal functional surfaces are prepared by the 3D metal laser sintering technology and the surface chemical reaction treatment technology together, so that the metal surfaces with different surface chemical compositions, surface roughness and surface geometric appearances are obtained. Inaddition, the chemical compositions, the surface roughness and the surface geometric appearances of the metal surfaces are continuously and monotonously changed, and the surface contact angles are ingradient change within the range of 150 degrees + / -15 degrees - 10 degrees + / -5 degrees.

Description

technical field [0001] The invention belongs to the technical surface treatment technology, and in particular relates to a method for preparing the surface of a bionic intelligent metal material by 3D printing. Background technique [0002] Biomimetic intelligent materials are new materials with perception, response and special functional capabilities, which are prepared through structural bionics and functional bionics by imitating various characteristics or characteristics of organisms based on the principles of bionics. As an important functional material, metals are widely used in various engineering fields. The preparation of multi-scale ordered metal surfaces with molecular, nano, and micro structures is an inherent requirement for the realization of biomimetic smart metal material surfaces. At present, the surface of biomimetic smart metal materials is mainly prepared by adjusting the chemical composition of the metal surface and constructing the microscopic morpholog...
