Description
Technical field
The invention belongs to technical field of metal formation, more particularly, to a kind of high alumina zinc-aluminium puppet alloy bar material and silk material.
Background technology
Corrosion is one of principal mode of hardware destruction, and metal erosion problem is to building, oil, bridge and ship etc.
Multiple industries bring imponderable loss, cause serious consequence.Because the consumption of steel is big, thus the corruption on steel
Erosion turns into the topmost problem of corrosion field, and the corrosion for reducing steel has huge social effect and economic implications.It is right at present
The conventional anti-corrosion method of steel component has cathode protection method, weathering steel, hot-dip, coating etc..Because coating and negative electrode are protected
Defending the doctrine has respective shortcoming, such as coating inevitably has certain gas permeability and seepage of water, cathode protection method protection
Scope is small, serious, short life affected by environment etc..And thermal jet zinc coating or aluminized coating are then due to having coating and negative electrode to protect simultaneously
The advantage defended the doctrine has good development prospect.Have particular application as that zinc or aluminum-alloy wire are sprayed into steel using hot-spraying technique
Component surface forms the metal cladding of even compact, can reach the steel component of the various corrosive environments of digital preservation.
Material used by current zinc or aluminium thermal spraying mainly has fine aluminium, pure zinc, Zn5Al alloys and Zn15Al alloys etc..Its
Middle pure aluminum coating contains of a relatively high porosity, and very sensitive to Cl- present in water, and spot corrosion easily occurs, and to machine
Tool damages also more sensitive.Pure spelter coating is in marine environment, weak acid environment and containing SO2Corrosion resistance in the environment of industrial atmosphere
Poor, rate of corrosion is higher so that the consumption of coating quickly, have impact on the anti-corrosion life of coating.Zn5Al's and Zn15Al is corrosion-resistant
Although performance will get well compared with the decay resistance of fine aluminium, pure zinc, still have much room for improvement.According to existing there are some researches show as Al contains
The raising of amount, coating surface tends to complete densification, and the less alloy coat of Al content is impervious not enough, penetrates readily through, corrosion resistant
Corrosion can be significantly lower than Al content alloy coat higher.
However, still there is certain, preparation method of current high alumina Aluminum Coating in the preparation of high alumina Aluminum Coating
There are hot dipping method, coating sintering process, powder cored filament material method and the pure zinc silk of electric arc spraying and fine aluminium silk method.Wherein hot-dip and coating
Sintering process can only be to processing, because the limitation both approaches of immersion plating pond and drying box cannot be entered to large-scale steel structure compared with small workpiece
Row protection.The complex process of powder cored filament material, and high-quality alloyed powder is relatively costly, now also in conceptual phase.If
When carrying out electric-arc thermal spray coating with one Zn and one Al, by adjusting the feed speed of two or the silk using different-diameter
Material is combined, and can prepare the Zn-Al pseudo alloy coatings of Al content high.But the defect of this coating is different silk material diameters
Or wire feed rate combination, cause atomization it is uneven, the composition of coating comes and go in regional area, so as to have impact on the property of coating
Energy.
In addition with the technique for carrying out thermal spraying to workpiece surface using high alumina Zn-Al alloy wire material, the high aluminum zinc used by it
Aluminium alloy silk material to be obtained using fine aluminium and pure Zinc smelting and obtained after drawing tube reducing is extruded after ingot casting, but this melting and casting process
In, fine aluminium and pure zinc form allumen, and the allumen for Al content more than 15%, and the content for continuing to increase Al can make
The formation of brittlement phase in alloy, causes the ingot casting for obtaining to be difficult to carry out drawing tube reducing to obtain silk material, difficulty of processing and processing cost
Greatly improve, limit the development and application of high alumina Zn-Al alloy wire material.How the thermal spraying Zn-Al alloy wire of high alumina is prepared
Material turns into the key of solve problem.Also have at present and prepare Zn-15~30Al's by the method for drawing using rolled tin cladding aluminium powder
The method that powder cored filament material carries out thermal spraying, but powder cored filament material spraying process is unstable, influences the performance of corrosion-inhibiting coating, Er Qiegao
The preparation of quality nano-powder and silk material use cost are higher.
