Embodiment Construction
[0031] The idea of the present invention is to use the principle of bionics to imitate the asymmetric structure and non-smooth surface morphological characteristics of the desert lizard body surface, and use various coupling elements such as materials, structures, and shapes to couple each other on the surface of nickel-chromium heat-resistant parts. Laser 3D printing is used to manufacture the bionic high-temperature erosion-resistant and wear-resistant working layer, which can give full play to the excellent wear-resistant and corrosion-resistant properties of ceramic materials, and at the same time take into account the impact resistance and fatigue resistance of the surface of the parts, making it have excellent anti-corrosion properties. High temperature erosion wear performance, improve service life and reduce cost.

Abstract
The invention relates to a coupling bionic component resistant to high-temperature erosive wear. The bionic component comprises a matrix and a bionic work layer prepared on the work face of the matrix. The matrix is chromated nickel heat resistant steel. The bionic work layer comprises a grid framework which is made of a nickel-based self-fluxing alloy and is of a bionic asymmetric structure and nickel-based metal ceramic, holes of the grid framework are filled with the nickel-based metal ceramic, and the nickel-based metal ceramic is provided with protrusion structures. The holes of the gridframework comprise the cylindrical holes, the prism-shaped holes and the regular-hexagonal-prism-shaped holes sequentially arranged in the grinding material ablation direction. The cylindrical holes and the regular-hexagonal-prism-shaped holes are arranged in a staggered manner, and the transition areas between the cylindrical holes and the regular-hexagonal-prism-shaped holes are filled with theprism-shaped holes to complete transition. According to the coupling bionic component, the high-temperature erosive wear resistance of the heat-resisting component can be obviously improved, the performance requirements for hardness and toughness can be achieved at the same time, good impact resistance and fatigue resistance are achieved, the service life of the component is prolonged, and meanwhile the production cost is greatly reduced.
Description
Technical field: [0001] The invention belongs to the technical field of high-temperature erosion-resistant components, in particular to a coupled bionic component resistant to high-temperature erosion and wear. Background technique: [0002] Abrasion is an important cause of material loss and equipment damage. In metallurgy, electric power, mining, building materials and chemical industries, huge waste and losses are caused every year due to material abrasion and corrosion. Among them, erosion wear accounts for about 8% of the total number of wear damage in industrial production, especially the damage caused by high temperature erosion wear to materials and equipment is more serious. Under high temperature wear conditions, hardness is the main factor determining wear resistance. As long as the hardness of the surface of the parts can be greatly improved, the wear resistance can be significantly improved. However, in general, the higher the hardness of heat-resistant cast s...
