Problems solved by technology

[0002] The current surface treatment, if a hole-like structure is required, requires laser high-energy drilling, or multi-layer lithography, 3D printing and other complex processes and formulations. At present, there is no effective method for manufacturing a hole-like structure on ceramics as a substrate.

Embodiment Construction

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0019] like figure 1 As shown, prepare a ceramic substrate, and clean the ceramic substrate to ensure that the surface is clean; then process nano-silicon dioxide, and apply nano-silicon dioxide on the surface of the ceramic substrate as the first layer; then prepare the metal oxide, Spray / spin the metal oxide on the upper surface of the nano-silica as the second layer; prepare a cleaning solution and apply it on the metal oxide of the second layer to dissolve the metal oxide and generate a porous structure, such as figure 2 shown.

[0020] Wherein, the metal oxide is a metal oxide that does not easily react with nano silicon dioxide. In this embodiment, the metal oxide is a CdTe / CdS / ZnS macromolecular metal oxide.

[0021] In this embodiment, the cleaning solution is a mixture of nitric ac...

Abstract

The invention discloses a method for forming a porous structure on a ceramic surface. The method comprises the following steps: preparing a ceramic substrate, and cleaning the ceramic substrate to ensure the cleanness of the surface; processing nano silicon dioxide, and smearing the nano silicon dioxide on the surface of the ceramic substrate to serve as a first layer; preparing a metal oxide, andspraying / spin-coating the metal oxide on the upper end surface of the nano silicon dioxide as a second layer; and preparing a cleaning solution and smearing the cleaning solution on the metal oxide of the second layer for dissolving the metal oxide to generate the porous structure. With application of the coating method and the traditional processing technology, the coating layer with the porousstructure can be rapidly manufactured and controlling can be realized through communication between holes.

Description

technical field [0001] The invention relates to a method for forming a porous structure on a ceramic surface. Background technique [0002] The current surface treatment, if a hole-like structure is required, requires laser high-energy drilling, or multi-layer lithography, 3D printing and other complex processes and formulations. At present, there is no effective method for manufacturing a hole-like structure on a ceramic substrate. . Contents of the invention [0003] The technical problem to be solved by the present invention is a method for forming a porous structure on the ceramic surface. By using a coating method and adopting a traditional processing technology, the coating with a porous structure can be quickly produced. [0004] The present invention is achieved through the following technical solutions: a method for forming a porous structure on a ceramic surface, which specifically includes the following steps: [0005] S1. Prepare a ceramic substrate, and clea...
