Description
Technical field
The utility model relates to a kind of spinning friction treatment device of workpiece coating, and it is applicable to improve material coating, and carrying is not the coating of coated electrode and the bonding strength of matrix, the compactness that improves coating, further improves the requirement in coated electrode life-span.
Background technology
Along with the development of automobile industry, general steel plate can not meet the needs that automobile is corrosion-resistant, lightweight develops.In order to meet future automobile industry development demand, various Coated Steels, particularly steel plate galvanized are applied more and more extensive on automobile.For energy-saving and emission-reduction, automotive light weight technology also becomes one of subject matter of automobile production industry consideration gradually simultaneously.Between automotive light weight technology development need, aluminium alloy plate manifests it gradually in the developing advantage of automotive light weight technology.Although the material of producing automobile has alternative, the method that its production technique can be selected for work is also few, and main method is still to be welded as master, and resistance spot welding has occupied the production (particularly vehicle body be take resistance spot welding substantially as main) of quite a lot of station.In Coated Steel or aluminium alloy plate pinpoint welding procedure, all expose too low problem of spot-wedling electrode life-span, this has in a disguised form increased produces consumption, makes also corresponding raising of production cost.For this problem, researchist has carried out further investigated, has obtained some fruitful achievements in research and has been applied to actual production.The most representative, by electric spark deposition technique, at spot-wedling electrode surface deposition one deck protecting materials (metal or sintering metal), the factors such as spot-wedling electrode alloying and viscous deformation that reduce with this are caused shorter problem of its life-span.
Electric spark deposition technology (electro spark deposition) is to utilize short pulse duration, the high-frequency pulse power that electrode materials is welded to a kind of pulsed arc microwelding technology in metal collective.The major advantage of electric spark deposition technology (ESD) is enough low heat inputs to be combined by electrode materials with matrix alloy.Thermal shocking effect during due to spark discharge, must follow the intrinsic defect of some these techniques, and Fig. 5 is holiday representative after spot-wedling electrode electric spark deposition (loose, crackle and coating is inhomogeneous)
The people such as Chen Zheng have also found problems when spot-wedling electrode electric discharge surface depositing Ti C coating, in order to repair these defects, the people such as Chen Zheng adopt laser remolten to carry out aftertreatment to the TiC coating on spot-wedling electrode surface, although the defect of coating is improved, but the life-span of electrode is not improved, major cause is that the too high electrode matrix that caused of laser temperature is annealed and softens.This illustrates from an aspect, can not be higher than the annealing temperature of electrode matrix (copper alloy) to the post-processing temperature of electrode surface coating, otherwise will cause electrode matrix softening.
Friction stir welding (Friction Stir Welding, be called for short FSW) be that Britain's institute of welding (The Welding Institute) is in the patent welding technique of invention in 1991, friction stir welding welding process is to be the seam crossing that mixing needle stretches into workpiece by the soldering tip of a cylindrical shape (welding pin), by the high speed rotating of soldering tip, make itself and welding work pieces material friction, thereby make the material temperature of connecting portion raise softening. material is carried out to agitating friction simultaneously and complete welding.In stirring friction-welding technique process, in order to reach the object of grain refining, investigator has done some researchs for different complete processings both at home and abroad, the ultrasonic wave of wherein usining is more as the report of subsidiary conditions crystal grain thinning, the field relating to is also wider, comprises casting, welding, and surface treatment.Representative, Kwanghyun Park has studied the equipment and process of the auxiliary friction stir spot welding of ultrasonic wave first, compares with Friction stir welding, and the auxiliary friction stir welding of ultrasonic wave can obtain the better welding joint of performance.
Agitating friction treatment technology is a kind of emerging composite material and preparation method thereof and the surface modification means of using for reference stirring friction-welding technique, because agitating friction is processed distinctive heat-mechanical equivalent of light feature, has been applied at present in the middle of surfacing preparation and processing.Week, little equality people processed (Chinese invention patent CN201010570898. by agitating friction
8al2O3+TiB2+Al compound coating of aluminum alloy surface reactive spray and friction Stir and preparation method thereof
),the Al2O3-TiB2 complex phase coating that thermospray is obtained has been carried out aftertreatment, found that coating is after agitating friction is processed, and its density, microhardness all make moderate progress.
Similar, Chinese invention patent " a kind of method (CN201310050662.5) of preparing Ultra-fine Grained/nanocrystalline sheet material based on ultrasonic semi-solid state assistant agitating friction complete processing ", " ultrasonic semi-solid state assistant agitating friction technological method for processing (CN 201310049003.X) under a kind of control cold environment ", " a kind of ultrasonic semi-solid state assistant agitating friction technological method for processing (CN 201310049927.X) of realizing material surface Ultra-fine Grained/nanometer ", these three patents have all adopted ultrasonic semi-solid state assistant agitating friction complete processing, but still adopted mixing needle to carry out surface treatment, make these three kinds of patent effects on surface coatings cannot carry out surface treatment.
Because agitating friction is processed and will coating be dug from matrix with mixing needle, the part basic material of simultaneously being dug can be sneaked in coating material, thereby cause the physics of coating or mechanical property to degenerate, agitating friction is processed in addition difficulty of processing and power consumption are also all excessive.
