Description
Technical field
The present invention is a kind of preparation method of Zn-Al bimetal composite material solid heart silk material, belongs to the field of thermal spray in the Materials Processing Engineering, and its finished product is mainly used in the each side such as anticorrosion, wear-resisting of boiler of power plant tube wall and boiler " four pipes ".
Background technology
Hot-spraying techniques is the spray material with fusion or semi-melting state, make its atomizing and be injected on the piece surface by the high speed electric current, form a kind of method of surface finish of spray-on coating, it can give surface abrasion resistance, anti-corrosion, high temperature resistant and other property.At present, the spraying method of hot-spraying techniques mainly comprises: electric arc spraying, flame plating, plasma spraying and four kinds of basic skills of special methods.Advantages such as wherein, electric arc spraying and flame plating is because it is easy and simple to handle, and coating result is good and being widely used.For the basic link that can ensure the quality of products in the spraying, the performance of spraying wire becomes a significant consideration in the modern project.Since the eighties in last century, emerging in large numbers of the fast development of hot-spraying techniques and high speed hot-spraying techniques makes that spraying molten drop speed improves in spraying process, and atomizing effect improves, and anchoring strength of coating increases, and porosity reduces.For improving coating quality, at present, Zn silk, Al silk and Zn-Al alloy silk are used widely in engineering.
Zinc is to use the earliest in the thermospray protection against corrosion construction, and maximum coated materials, and at present, the pure spelter coating of thermospray remains the first-selected processing method of the important steel structural part that protection is on active service under atmosphere, fresh water environment.Compare with the fine aluminium coating, the corrosion resistance nature of Zn-Al alloy is higher, and under multiple environment for use, identical coat-thickness is by the longer protection life-span.Simultaneously, with the coating that Zn-Al alloy sprays out, the corrosion product of its coating is few, and void content is few, has quick self-enclosed characteristic, and outward appearance is better.
The Zn-Al alloy that thermospray is used mainly is the zinc-aluminium binary alloy that contains Al amount 5%-30%.Commonly used is to contain zinc 85% at present, the binary aluminium zinc of aluminum content 15%.The general trade mark of this alloy is Zn-Al15.
In the process of preparation Zn-Al alloy coating, because the specific gravity difference of zinc-aluminium two-phase element is big, thereby is easy to cause gravity segregation when smelting, cause the metallurgy melting difficulty, influence coating quality; In preparation during coating, improve the content of Aluminum in Alloy after, can cause the alloy hardening to become fragile, be difficult to drawing, tube reducing is made a material, has had a strong impact on the application and the development of Aluminum Coating.At this situation, aluminum zinc powder core Spray Wire has also appearred at present, but the powder cored filament material of this alloy powder preparation is owing to limited by filling ratio, the content of Al has only 5-30% in the powder cored filament material, promptly the Al content in the silk material can not surpass 30%, can't reach the optimum content ratio of zinc-aluminium, and the preparation method of the designed bimetallic composite wire material of patent of the present invention, utilize the zinc band to coat the method for solid aluminium wire, in the process of spraying heating be two kinds of metal meltings together, reach the coating of preparation bimetallic alloy performance, and wherein aluminium content can reach 40%, has solved Al content effectively and must not be higher than 30% this problem.
Summary of the invention
The final purpose that the present invention will reach is: can prepare a kind of Zn-Al binary metal alloy used for hot spraying solid core wire material with method of the present invention, its preparation method is simple, the preparation efficiency height.Using this solid core wire material, can be two kinds of metal meltings under heating condition in spraying process, thereby prepare the Zn-Al alloy coating, its coating corrosion resistance is good, solves the revolving furnace fume hood tube wall and produces high temperature oxidation and corrosion and erosive wear problem, guarantees the safe operation of steelwork converter.The present invention can improve metal structural component and use properties, the reenlist life-span of device feature in harsh corrosive wear environment.
A kind of method for preparing used for hot spraying Zn-Al bimetal solid core wire material provided by the present invention is characterized in that the preparation method is simple, efficient is high, and described solid core wire material medicinal powder composition quality percentage composition scope is as follows:
Al:20～45%, Zn: surplus.
Preparation method of the present invention adopts prior art, may further comprise the steps:
1) core material is the aluminium wire of 1.6～3.0mm different diameter.
2) skin material is aluminium zinc band and the pure zinc band that aluminum content is about 10% (massfraction), and the surface utilizes the powder cored filament material maker to be processed into the zinc-aluminium bimetallic composite wire material of required diameter through after thoroughly clearing up.
With thickness is the band that the skin material of 0.3～0.5mm is cut into 10～14mm, according to the procedure of processing of powder cored filament material, progressively is rolled into the cross section of " U " type through three groups of rolls of wire coating machine; Send in " U " type band with above-mentioned a kind of core silk material this moment, replace and to send a part device automatically in the powder cored filament material course of processing, butt joint roller by wire coating machine rolls " U " type band to close and forms lap joint with solid silk parcel then, through the follow-up pressure roller in three roads " U " band progressively is pressed into " O " type and compacting, at this moment " O " type composite wire be admitted to drawing wire machine through 8～14 road drawings gradually tube reducing become the finished product zinc-aluminium bimetallic composite wire of required diameter.
