Abstract

The invention relates to a wear-resistant hydrophobic nano composite film and a preparation method thereof, belonging to the technical field of metal surface treatment and modification. The composite film is based on high-speed steel, or titanium alloy, or hard alloy, or pure metal, and a pure metal film and a microstructure nano composite film are sequentially prepared on the base surface. The preparation method comprises the following steps: depositing a nano composite hard film with excellent mechanical properties on the base material surface by arc ion plating, and generating a micro / nano dual structure on the film surface by an ultra-fast laser processing technique to obtain the surface film with favorable mechanical properties and certain hydrophobicity. The film maintains excellent mechanical properties of the nano composite hard film: high surface hardness, high toughness, high wearability and high scratch resistance; and the microstructure on the film surface is constructed, so that the film has certain hydrophobicity. The preparation method has the advantages of simpler equipment, low cost, low energy consumption and no pollution, and can implement efficient green manufacturing.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment and modification, and in particular relates to a wear-resistant hydrophobic nanocomposite film and a preparation method thereof. Background technique [0002] With the rapid development of modern manufacturing industry and the continuous complexity of the service environment of materials, the use of hard films for surface modification has gradually become an important way to protect the surface of materials. At the same time, higher and higher requirements have been put forward for the performance of hard films. Require. In many harsh service environments, such as the anti-icing of the air intake of the carrier-based aircraft engine, the marine anti-corrosion of the metal on the surface of the ship, etc., the hard film is required to have strong comprehensive properties. On the one hand, it must have excellent mechanical properties. , in order to improve the wear resistance and fr...
