Abstract
The invention discloses a kind of bionical Anti-erosion surface texture, the present invention is the back feature based on desert scorpion, on engineering material surface, design has V-groove, convex closure, regular hexagon pit, can be applied to the various easy structure members by erosion to improve its anti-erosion property.V-groove distribution parallel to each other, section is equilateral triangle；Convex closure size uniformity is distributed on the ridge of V-groove；Regular hexagon pit is evenly distributed between convex closure structure.Biomimetic features of the invention be combined with each other synergy change material surface Dual-Phrase Distribution of Gas olid flow regime, reduce the number of times of solid particle impingement material surface, and the speed that material surface is clashed into the presence of the mattress of counterclockwise rotates of the solid particle inside V-groove and regular hexagon pit is substantially reduced, and then cause that the erosion rate in erosion process of the material with these micro-structurals diminishes, improve the anti-erosion property of material.
Description
Technical field
The present invention relates to a kind of surface texture, more particularly to a kind of bionical Anti-erosion surface texture.
Background technology
Solids washout abrasion is due to mechanical surface and with the interaction between the solid particle of certain speed motion
Cause the loss of surface quality.It can make engineering material produce crack, and the durability of industrial products is reduced and also resulted in big
Potential safety problem of amount etc..In order to solve this solids washout wear problem, previous research can be divided three classes:It is compound
Material, material modification and face coat.For composite, it has good with single metal alloy and polymer phase ratio
Intensity and low-density characteristic, the extensive use in terms of Aero-Space Anti-erosion, but technical difficulty is larger, construction period
It is long, high cost；Material modification is to improve its erosion wear resistance by changing material internal microstructure, but mechanical in itself by material
Performance is limited, and effect is limited；Including the coating and the thickness of coating for spraying etc., this can be reduced face coat to a certain extent
Its erosion, but anchoring strength of coating is limited, easily comes off, and manufacturing process is complicated, high cost.
With deepening continuously for bionics Study, many science and technology problems can obtain inspiration from living nature.It is husky
Unconcerned scorpion lives in severe desert area, is frequently subjected to the erosion of dust storm.They are in order to adapt to bar of the existence in natural selection
Backboard is enterprising under part dissolves special structure, and it includes V-groove, convex closure and regular hexagon bowl configurations.These structure phase interworkings
Close, act synergistically, natural biological source is provided to manufacture and design bionical anti-impact corrosion material.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, and provide a kind of bionical Anti-erosion surface texture.
The present invention is, based on the excellent Anti-erosion cuticle topography form of desert scorpion, to design V-groove, convex closure, regular hexagon
Bowl configurations, these structures can change the gas-particle two-phase of material surface under the high speed impact of different size of solid particle
The flow regime of stream and the impact velocity of reduction solid particle, such that it is able to reduce erosion rate of the material in erosion process, carry
Its anti-erosion property high.
Design philosophy of the invention is the V-groove from desert scorpion back plate surface, convex closure, regular hexagon bowl configurations.
Micro-structural to desert scorpion back plate surface carries out signature analysis, and to improve material surface anti-erosion property as target is tried
Test optimization design, it is determined that the design of bionical Anti-erosion surface texture.
The present invention is to offer some V-grooves on engineering material surface, some parallel distributions of V-groove, two adjacent V-grooves it
Between ridge width it is identical, on the ridge of V-groove have convex closure and regular hexagon pit.
The length of side a of described V-groove is 4mm, and V-groove two edges spacing b is 4mm, and the section of V-groove is equilateral triangle
Shape.The width c of the ridge is 4mm.
Described convex closure is evenly distributed on the ridge of V-groove, and the protrusion diameter d of convex closure is half spheroid of 1mm, adjacent convex
Spacing e between bag is 2mm.
The regular hexagon pit is located between the adjacent convex closure on V-groove ridge, and convex closure is distributed two row on each ridge.With
On the basis of ridge plane, the downward pit depth f of regular hexagon pit is 0.3mm, and length of side g is 0.5mm, and regular hexagon pit is at each
Distribution four is arranged on ridge.
The present invention can be applied to the easily mechanism by erosive wear or part, to improve its anti-erosion property, so as to extend
Its service life.
Biomimetic features of the invention can change the flow regime of the Dual-Phrase Distribution of Gas olid of material surface, reduce solid particle and hit
Hit the number of times of material surface, and due to inside grooves counterclockwise rotates mattress effect, reduce solids
The speed of whereabouts and then reduce solids and clash into the kinetic energy of material surface so that material is in different size solid particle
Erosion rate is reduced in erosion process, its anti-erosion property is improved.
Beneficial effects of the present invention：
The present invention carries out coating without change engineering material material internal microstructure and without in material surface, only
It is to set bionical micro-structural on engineering material surface can just improve the anti-erosion property of structure or part, with manufacturing process letter
Single, technical difficulty is small, takes few, the advantage of low cost.
