Description
Technical Field
The invention relates to the technical field of metal materials, in particular to a high-precision structural member material for multi-energy field composite surface post-treatment and a preparation method thereof.
Background
The high-precision structural member refers to a metal or plastic part which has high dimensional accuracy, high surface quality and high performance requirements and can play a role in protection, support or heat dissipation. As a key intermediate product in the industrial field, the product has the advantages of strong product stability, good fatigue resistance and attenuation resistance, high processing precision, good surface finish and the like, and is widely applied to the fields of communication equipment, new energy, automobiles, consumer electronics, aerospace, industrial automation and the like. With further expansion of application range, requirements for miniaturization, high precision, high texture, high reliability and other characteristics of high-precision structural parts which are important components indispensable for a plurality of high-precision products are continuously increased. The development of high-precision structural members with excellent comprehensive performance and performance stability is a difficult problem to be solved by researchers in the industry.
In order to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product, surface treatment is required on the surface of the structural member material. The surface treatment is a process of artificially forming a surface layer on the surface of a base material, which layer has different mechanical, physical and chemical properties from those of the base. However, the surface roughness of the high-precision structural member material obtained by the existing surface treatment process method of the high-precision structural member material is large, and the use requirement cannot be met; meanwhile, surface embedding of surface treating agent particles is easy to be caused due to deeper surface damage and unreasonable particle size design of the surface treating agent particles, and adverse effects are brought to surface treatment quality. In addition, due to the adoption of single energy field surface treatment, the preparation efficiency, precision and surface microscopic quality of the existing high-precision structural member material are difficult to consider, and the corrosion resistance and the wear resistance are required to be further improved.
In order to solve the above problems, chinese patent application number 200910110550.8 discloses a surface treatment method for steel structural members, comprising the steps of: A. removing oil and rust on the surface of the steel structural member; B. treating the surface of the steel structural member by adopting a zinc-aluminum co-permeation method, and forming a co-permeation layer on the surface of the steel structural member; C. removing an oxide film on the surface of the steel structural member treated by adopting a zinc-aluminum co-permeation method by adopting a shot blasting method; D. treating the surface of the shot-blasted steel structural member by adopting a Dacromet technology, and forming a Dacromet coating on the surface of the steel structural member; E. coating a coating with good permeability on the surface of the Dacromet coating to seal micropores on the surface, and forming a surface protection layer of the steel structural member together with the co-permeation layer and the Dacromet coating. The invention fully plays the advantages of the penetrating coating, the Dacromet and the coating, and forms a good wear-resistant and corrosion-resistant surface protection layer on the surface of the steel structural member. However, the precision of the structural member and the microscopic quality of the surface still remain to be further improved, and the corrosion resistance and the wear resistance still remain to be further improved.
Therefore, the development of the high-precision structural member material with the multi-energy-field composite surface post-treatment and the preparation method thereof meet the market demand, have wide market value and application prospect, and have great significance in promoting the development of the multi-energy-field composite surface post-treatment technology and the high-precision structural member field.
Disclosure of Invention
In view of the above problems, the present invention aims to provide a high-precision structural member material for multi-energy-field composite surface post-treatment, which has the advantages of good mechanical properties, good corrosion resistance and wear resistance, and excellent fatigue resistance, and a preparation method thereof.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: the high-precision structural member material for the multi-energy field composite surface aftertreatment sequentially comprises a substrate, a cladding layer and a finish paint layer from inside to outside; the matrix is prepared from the following components in percentage by weight of ：Mo 0.1wt％-0.8wt％、Cr 0.1wt％-0.5wt％、Nb 0.05wt％-0.2wt％、Re0.006wt％-0.01wt％、Ga 0.003wt％-0.008wt％、Os 0.005wt％-0.008wt％、Ti 0.1wt％-0.3wt％、Sr0.001wt％-0.003wt％、 rare earth elements 0.06-0.1 wt%, B0.001-0.003 wt% and the balance of Cu.
