Description
Technical field
The present invention relates to a kind of method for surface hardening of copper zinc alloy, belong to the processing technique field of metallic substance.
Background technology
Copper and copper alloy because having the advantages such as outstanding electroconductibility, thermal conductivity, sight, solidity to corrosion and good mechanical property large-scale application in information communication, machinofacture, electrically, electronics, building, chemical industry, the energy, the modern project technical field such as national defense industry.Various electronic product, household electrical appliance, industrial plants etc. all be unable to do without copper and copper alloy product, and they have been produce and irreplaceable important engineering materials in life.
Copper zinc alloy has good mechanical property, processing performance and solidity to corrosion, and what have also has higher electroconductibility and machinability, is purposes material the most widely in copper alloy.Along with the fast development of industrial technology, traditional working method has been difficult to meet demand to high performance material gradually, it is also proposed higher index to the intensity of copper zinc alloy and plasticity.Superfine crystal particle metallic substance is prepared in conventional large plastometric set method such as Equal Channel Angular Pressing, high pressure torsion, ply rolling etc. at present, by significantly refining grain size, form a large amount of crystal boundary and effectively hinder dislocation motion, intensity can be greatly improved, but bulk ultrafine-grained materials room-temperature tensile plasticity is very low.High strength and high-ductility become a pair conflicting characteristic, and current preparation method improves its Some Mechanical Properties in the mode of sacrificing plasticity or intensity usually to a certain extent, and cannot really reach optimizing integration of the two.
The free energy of making Nano surface by adopting non-equilibrium treatment process to increase polycrystalline material surface, thus surface grain size is reduced gradually, under the repeat function of plus load, through the intense plastic strain of different directions, the open grain structure refinement gradually of material surface, finally reaches nanometer scale.After making Nano surface, the grain-size of material increases gradually along thickness direction, the physical dimension of material remains unchanged substantially, and there is not obvious interface between surface nanometer layer and matrix, there will not be the phenomenon such as interface pollution and stripping, provide more excellent approach for nanotechnology and conventional material combine.
The present invention utilizes high energy ball mill to carry out Surface Nanocrystalline to copper zinc alloy sheet material, preparation table mask has the Gradient Materials of nanometer-superfine crystal particle, top layer has high intensity, hardness, and core still retains higher plasticity, the graded of crystal grain makes to adopt the copper zinc alloy of the method process to have extremely excellent performance.
Summary of the invention
The object of this invention is to provide a kind of method for surface hardening of copper zinc alloy, change the gradient material that copper zinc alloy plate surface layer is stable Ultra-fine Grained, thus prepare the method for the gradient copper zinc alloy of comprehensive mechanical property excellence, the method complete processing is simple, specifically comprises the following steps:
(1) copper zinc alloy sheet material is annealed 1 ~ 2 hour at the temperature of 800 ~ 850 DEG C;
(2) step (1) gained sheet material is carried out surface finish, immediately under vacuum or liquid nitrogen environment, Surface Nanocrystalline is carried out to the copper zinc alloy sheet material after polishing, obtain the copper zinc alloy of high strength and high-ductility.
When processing under vacuum conditions described in step of the present invention (2), treatment temp is room temperature.
Surface Nanocrystalline process described in step of the present invention (2) uses high energy ball mill to complete, and test frequency is 20 ~ 50Hz, and steel ball is 100-200, diameter 8 ~ 10mm, treatment time 5 ~ 30min.
The invention has the beneficial effects as follows:
Surface Hardening Treatment mode of the present invention is by carrying out high strain rate shock to copper zinc alloy surface, make surface microstructure progressively refinement formation gradient crystalline-granular texture, in deformation process, surface fine grain layer and coarse-grain matrix are coordinated mutually, number of mechanisms cooperatively interacts, effectively prevent feature size suddenly change cause performance sudden change, thus copper zinc alloy plate intensity and plasticity are improved simultaneously, its yield strength promotes more than 2 times and can keep good unit elongation, processing mode is simple, be easy to realize continuous prodution, constant product quality, equipment funds input ratio is less, easy to maintenance, widen the range of application of copper zinc alloy.
