A kind of erosion-resistant hydrophobic material and preparation method thereof

Abstract

The invention discloses an erosion-resisting hydrophobic material and a preparation method of the material. According to the preparation method of the erosion-resisting hydrophobic material, a magnetic filtering negative electrode vacuum arc discharging method is adopted to enable a plurality of film layers to be deposited on the surface of a workpiece; and a laser device laser etching method is adopted to etch texture on the surface of the workpiece after film layer deposition, wherein the film layer deposition step is carried out before the texture etching step. The prepared multi-layer film of specific structure has the excellent wear-resisting impact-resisting performance, and the service life of engineering structural parts under the contact abrasion and impact environment can be obviously prolonged; due to instruction of a film layer system, the hardness of a base body is improved, the shaping and deformation resistance capacity of the base body is improved, and erosion-resisting and abrasion-resisting performance of the base body is further improved; and due to instruction of a microstructure, the capacity of oil / grease storage and wear particle containing can be effectively improved, and on the premise that the hydrophobic property is ensured, the service life of the film layer is further improved.

Description

Technical field [0001] The invention relates to the field of surface modification, in particular to a method for preparing a hydrophobic coating on a metal surface. The invention also relates to the erosion-resistant hydrophobic material prepared by the above method. Background technique [0002] The icing of flight components is one of the important factors affecting the safety of the entire flight system. According to statistics, about 9% of aircraft accidents are caused by surface icing. When an airplane flies in icy conditions, the flight quality and flight performance will be greatly affected. Icing will not only increase the weight of the aircraft, reduce the efficiency of the propeller, and thus reduce the available thrust of the engine, but also interfere with the airflow, resulting in increased drag and reduced lift. In the 1940s and 1950s, people did a lot of work on aircraft icing and anti-icing. On the one hand, they improved the anti-icing devices of aircraft, and ...
