The larger difference of the performances such as coefficient, elasticity modulus and thermal coefficient will be produced using component surface entirety coating processes on surface
Raw biggish thermal stress, the crackle easily generated under the collective effect of thermal stress and extraneous load, since coat hardness is higher, only
Split that ability is poor, crackle easily extension removing for leading to coating and matrix under action of pulling stress influences the wearability of material surface；
Secondly, Laser Surface Cladding Technology ceramic process belongs to the bulk modified technique of component surface, cost of manufacture is higher, and still without
Method solves the problems, such as that component surface impact resistance difference and anti-fatigue ability are weak at all.
2. metal matrix ceramic composites technology of preparing
Its cardinal principle is with metal by heat-resist, hardness is big, but not impact-resistant metal oxide, carbide, nitrogen
Compound etc. is bonded together, the certain plastic deformation generated under external force by ductility phase (metal) particle or crystal boundary position
It moves the creep generated and absorbs portion of energy, alleviate stress and concentrate, to achieve the purpose that increase toughness.(ceramic on metal is compound

Key point of the invention is:
First, the morphological feature of desert lizard body surface is imitated using bionics principle, it is more using material, structure, form etc.
Bionical working lining of the mode that kind coupling member intercouples in the preparation high temperature resistant erosive wear of nickel chromium triangle series heat-resistant steel matrix working face, tool
There are bionical unsymmetric structure, non-smooth surface feature, can adapt to each position of heat-resisting components due to the variation pair of erosion operating condition
The influence of overall wear resistance, such as the variation of abrasive material size, shock loading, erosion direction factor, can dramatically improve
Heat-resisting components high temperature resistant erosive wear ability, while there are the performance characteristics of soft and hard alternation, tough combination, improve heat-resisting zero
Component shock resistance, antifatigue performance, help to improve service life, reduce cost.
Second, imitative in the preparation high temperature resistant erosive wear of nickel chromium triangle series heat-resistant steel matrix working face by the way of laser 3D printing
Raw working lining, the accuracy of manufacture for improving bionical working lining of high degree, and prepared for mimic biology body surface complex topography
Bionical working lining provides technical support；To have high rigidity, high-wearing feature and height resistance under high temperature using laser 3D printing technology
Corrosion nickel based metal ceramic material insertion have high tenacity, high corrosion-resistant nickel base self-fluxing alloy powder made of it is bionical non-
In the grid frame of symmetrical structure, can be realized wear-resistant material and the good metallurgical bonding of matrix surface, by soft matrix and
The bionical good coating function of unsymmetric structure grid frame can high degree improve the bionical impact-resistant performance of working lining, prevent
The only generation of bionical working lining fatigue and peeling phenomenon, improves the service life of heat-resisting components.This method has technique letter
The features such as list, high production efficiency, design flexibility are big, the accuracy of manufacture is high, service life is high, manufacturing cost is low.
In addition, being formed in heat-resisting component surface has certain regularly arranged asymmetric bulge-structure, it is described non-right
Title type bulge-structure can be according to the difference of heat-resisting components each position actual wear operating condition in actual production, such as along erosion
The variation of the factors such as the direction abrasive material size of abrasion, shock loading, erosion direction, for the specific wear working condition in each position of components
It designs and the positive six prismatic table shapes protrusion knot of large scale is changed by intensive small size hemisphere jut along abrasive material erosive wear direction
The bionical asymmetric bulge-structure feature of structure.Intensive small size hemisphere jut structure distribution in the front end of heat-resisting components,
Abrasive material is contacted first, can be given full play to the preferable impact resistance of hemisphere jut structure, be resisted biggish impact, while small ruler
Very little hemisphere jut structure intensity distribution, can effectively prevent by means of the coating function of high tenacity grid frame and soft matrix
The extension of crackle improves antifatigue ability；Positive six prismatic table shape of large scale is distributed in the end of heat-resisting components, the impact of abrasive material
