Description
Technical field
This utility model is related to a kind of pricker and applies material, especially relates to a kind of lamellar composite pricker and applies material.
Background technology
In mechanical field, some workpiece local surfaces often require that there is higher wearability and corrosion resistance.If will
One-piece machine member all uses antifriction alloy or corrosion-resistant material manufacture, not only relatively costly, and past at aspects such as overall mechanical properties
Toward again requirement can not be met.Rational solution is typically with process for treating surface, coats on the work surface of workpiece
One layer of wear-resisting or anti-corrosion metal or alloy.For wearing layer, conventional method has physical vaporous deposition (PVD), chemistry
Vapour deposition process (CVD), hot spray process, welding method and pricker coating.The heavy method of physical vapor and chemical vapour deposition technique can only obtain
Very thin coating；Plasma spraying and flame-spraying typically can only achieve the thick coating of about 1mm；The heating-up temperature of surface overlaying method
Higher, easily produce thermal stress, layer is typically relatively thin；Pricker applies rule difference, can obtain thickness range than larger with pricker coating
Coating（From 0.05mm the thinnest to relatively thicker 4mm）.In addition, pricker coating and mother metal system metallurgical binding, bond strength specific heat
The mechanical bond of spraying is much higher；Simultaneously pricker apply than built-up welding when heating-up temperature low, the change of thermal stress and mother metal performance is relatively
Little；And pricker coating surface is smooth, construction precision is high, can reach permissible accuracy through too small amount of processing.
Pricker used in pricker coating applies material and is made up of two parts：A part is brazing filler metal alloy, and its fusion temperature is relatively low,
Common name low-melting component；Another part is the high hard alloy of fusing point, is generally called high melting point component.Traditional pricker applies material and is typically
The pulp-like pricker that powdered filler metal, hard alloy particle, bonding agent, Organic substance etc. are prepared into suspension applies material or lamellar pricker applies material
Material, is then coated with or is bonded in surface of the work, for preventing mother metal, the oxidation of powdered filler metal and promoting solder in hard alloy
Grain, the wetting and spreading on mother metal surface, pricker generally requires constantly to add brazing flux during applying, inefficiency and easily cause brazing flux
A large amount of wastes, relatively costly.
Content of the invention
The purpose of this utility model is to provide a kind of lamellar composite pricker easy to use to apply material.
For achieving the above object, this utility model can take following technical proposals：
Lamellar composite pricker described in the utility model applies material, and it is by brazing filler metal alloy internal layer, includes hard alloy particle
Mixture middle level and the brazing filler metal alloy outer layer banded structure being rolled into or the tubular structure being drawn into brazing flux.
The thickness of described brazing filler metal alloy internal layer is 0.01～1mm, and the thickness in described mixture middle level is 0.1～4mm, described
The thickness of brazing filler metal alloy outer layer is 0.1～2mm.
The utility model has the advantage of it is good to carry brazing flux, formability, pricker achieves during applying that brazing flux is quantitative, automatically adds
Plus；Brazing filler metal alloy and hard alloy ratio are consistent, and pricker can apply quality by effective guarantee pricker during applying；The lamellar composite of roll forming
Pricker applies material and can roll discoid or shaft-like, is easy to deposit and transports, and pricker can realize automated production during applying.
Brief description
Fig. 1, Fig. 2 are structural representations of the present utility model.
Fig. 3 is to roll discoid lamellar composite pricker to apply material.
Specific embodiment
Lamellar composite pricker described in the utility model applies material, be by brazing filler metal alloy internal layer 1, include hard alloy particle and
The banded structure that the mixture middle level 2 of brazing flux and brazing filler metal alloy outer layer 3 are rolled into, as shown in Figure 1；Can also be rolled by multiple tracks
System, coating（Hard alloy particle, brazing flux, the mixture of organic adhesive）, drawing, the operation such as alignment make tubular structure, such as
Shown in Fig. 2.Rolling or the good lamellar composite pricker of drawing apply material can roll discoid（As shown in Figure 3）, deposit, transport to facilitate
Defeated, also it is beneficial to automated production simultaneously.
The thickness of wherein brazing filler metal alloy internal layer 1 is 0.01～1mm, and the thickness in mixture middle level 2 is 0.1～4mm, and solder closes
The thickness of golden outer layer 3 is 0.1～2mm.
Wherein brazing filler metal alloy can be silver-base solder, nickel-based solder, copper base solder etc., and mixture middle level 2 is to be closed by hard
Gold grain, general brazing flux and organic adhesive are formulated by a certain percentage.
When banding pricker applies material preparation：
The mixture prepared hard alloy particle, brazing flux and organic binder bond by a certain percentage first is coated uniformly on pricker
Material alloy surface, then places certain thickness brazing filler metal alloy again on mixture surface, is rolled into required thickness using finishing rolling mill
Three layers of compound pricker of the banded structure being made up of brazing filler metal alloy internal layer 1, mixture middle level 2 and brazing filler metal alloy outer layer 3 of degree apply material
Material finished product；
When tubulose pricker applies material preparation：
The mixture prepared hard alloy particle, brazing flux and organic binder bond by a certain percentage first is coated uniformly on pipe
Then strip brazing material alloy is rolled through multiple tracks, this tubular solder alloy-coated is drawn by multiple tracks by shape brazing filler metal alloy surface
Pull out, alignment process, make the three of the tubular structure being made up of brazing filler metal alloy internal layer 1, mixture middle level 2 and brazing filler metal alloy outer layer 3
The compound pricker of layer applies finished material.
