Bionic anti-erosion surface with composite coating adhesive

Abstract

The invention discloses a bionic anti-erosion surface with a composite coating adhesive, and belongs to the field of surface engineering. Based on a surface skin structure of a desert lizard body, a bionic structure with an anti-erosion function is designed. The bionic anti-erosion surface consists of three layers sequentially including an isolation protective layer, an adhesion layer and a bionic functional layer from a surface of a basal body to outside. The isolation protective layer adopts a thin release paper material and mainly plays a role in storing colloids; the adhesion layer adopts a hot melt adhesive film and is used for fixing a colloid connecting metal part; the bionic functional layer consists of a soft layer and a hard layer, and hard layer unit bodies are round and bumped and are regularly arranged without being adhered to each other. An erosion experiment and numerical simulation prove that the structure has good tolerance ability on erosion of abrasive grains. The bionic anti-erosion surface disclosed by the invention is easy to process, is low in cost, is convenient to use and is suitable for being used in surfaces of all complicated machines; moreover, the bionic anti-erosion surface has good anti-erosion performance, and can be widely applied to the field of surface engineering of engineering machinery.

Description

technical field [0001] The invention relates to the technical field of engineering machinery surface engineering, in particular to a bionic anti-erosion surface with composite coating glue. Background technique [0002] Erosion wear widely exists in machinery, metallurgy, energy, chemical industry, aerospace and many other departments, and the harm it brings can be seen everywhere: Erosion wear widely exists in fans, water pumps, turbine blades, propellers, etc. main cause of wear and tear. [0003] In order to reduce the impact of erosion damage in industrial production, new materials reinforced by fibers and polymers, surface material modification and strengthening, engineering design and two-phase flow characteristics have been changed, and certain effects have been achieved. . However, these methods often have complex processes or designs, long engineering cycles, high costs, are limited by the mechanical properties of the materials themselves, and do not involve the i...
