Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 As shown, a 304 stainless steel surface multi-coupled super-hydrophobic preparation process, the preparation process includes the following steps:

[0019] Step 1: Initial grinding treatment: Grind the substrate on 600-mesh, 1000-mesh, 1500-mesh, 2000-mesh sandpaper in order to make the surface smooth;

[0020] Step 2: Polishing treatment: Polish the substrate that has been initially ground on a polishing machine to make the surface of the substrate smooth; then place the polished substrate in deionized water for ultrasonic cleaning for 4 minutes and then use deionized water Rinse for 30s;

[0021] Step 3: Sandblasting for the first time on the surface of the substrate: put the substrate in the spraying room for sandblasting process, the sandblasting parameters are: sandblasting pressure 0.55MP, sandblasting sand grains ...

Abstract

The invention discloses a 304 stainless steel surface multielement coupling super-hydrophobic preparation method, and belongs to the field of metal part and material surface super hydrophobicity. The304 stainless steel surface multielement coupling super-hydrophobic preparation method is capable of solving the adverse hydrophobic problem of the surface of prepared 304 stainless steel. The 304 stainless steel surface multielement coupling super-hydrophobic preparation method comprises following steps: polishing, a first time of sandblasting, monopulse deposition, a second time of sandblasting,and drying. The 304 stainless steel surface multielement coupling super-hydrophobic preparation method is capable of obtaining grading scale structures (submillimeter grade, and micrometer-nanometergrade) of the 304 stainless steel hydrophobic surface, wherein the scale of a cauliflower-like protruding main structure formed through monopulse deposition on a matrix is micrometer-nanometer grade,the scale of second time sandblasting formed surface destroyed cauliflower-like protrudings and protruding gaps is submillimeter grade; a rough structure formed through the first time of sandblastingis capable of increasing the bonding force of the coating layer with the matrix, a rough structure formed through the second time of sandblasting is capable of forming a multi-scale multi-stage microstructure on coating surfaces, and surface hydrophobicity is improved.

Description

technical field [0001] The invention relates to the field of superhydrophobic preparation of metal parts and material surfaces, in particular to a preparation process for multi-component coupling superhydrophobicity on the surface of 304 stainless steel. Background technique [0002] In modern industrial production and daily life, stainless steel plays an irreplaceable role. Due to its good mechanical properties, low temperature resistance, corrosion resistance, wear resistance and excellent process performance, it has been widely used in various industries, including automobiles, kitchen utensils, ships, aviation industry and medical equipment. With the development of industrial modernization, people's requirements for the performance and process performance of stainless steel materials are constantly improving. The traditional surface properties of stainless steel can no longer meet the requirements of multi-functional composites. At present, the surface modification of st...
