Abstract

The invention discloses a hard hydrophobic coating with a micro-nano structure and a preparation method of the hard hydrophobic coating, and relates to the field of hydrophobic coatings. According tothe preparation method disclosed by the invention, a Cr layer and a CrTiAlN layer are sequentially deposited by adopting multi-arc ion plating equipment with an ion beam auxiliary device, then irradiation is carried out by using a medium-energy carbon ion beam, carbon ions are injected into the CrTiAlN layer while etching is carried out, and CrTiAlCN metal carbide is formed. The metal carbide hashardness higher than that of nitride of the metal carbide, so that hardness and wear resistance of the whole coating are further improved; the CrTiAlCN obtained after medium-energy carbon ion beam treatment is improved in hydrophobicity on the basis of reserving the hard wear resistance of the CrTiAlN layer; and the carbon also has good anti-friction self-lubricating performance, so that surface abrasion of the coating and adhesion to high polymer material of the coating are reduced. The preparation method provided by the invention is simple in process and can be directly applied to industriallarge-scale production.

Description

technical field [0001] The invention relates to the field of hydrophobic coatings, in particular to a hard hydrophobic coating with a micro-nano structure and a preparation method thereof. Background technique [0002] It is the most commonly used method in the industry to produce plastic, rubber and other polymer material parts with specific shapes through mold injection molding, which has a huge production scale and is widely used. One of the biggest difficulties in its production process is to solve the adhesion problem between the molded part and the mold, that is, to enhance the release property of the mold. Generally, the method commonly used in industry to enhance the release performance of molds is to use release agents, but release agents have disadvantages such as high price, great harm to human body, and corrosive effect on molds, which are uneconomical and not environmentally friendly. There is an urgent need for better alternative technologies. By preparing a ...
