Description
Technical field
The present invention relates to pricker and be coated with material, especially relate to a kind of compound pricker and be coated with material, the invention still further relates to this compound pricker and be coated with
The preparation method of material.
Background technology
Hard alloy has high rigidity, the advantage such as wear-resistant and corrosion-resistant, and some parts locally surface often requires that have
Higher wearability and corrosion resistance, if part is by overall hard alloy manufacture, the most relatively costly, and in body force
Learn the aspects such as performance and can not meet the most again requirement.By physical vaporous deposition (PVD), chemical vapour deposition technique (CVD), heat
The methods such as spraying process, welding method and pricker coating can improve the resistance to of piece surface at piece surface one layer of hard alloy of coating
Mill, the performance such as corrosion-resistant.Physical vapor sinks method and chemical vapour deposition technique can only obtain the thinnest coating, and price is higher, makes
Bigger by limitation；Thermally sprayed coating is the coating of a kind of mechanical snap, and coating is poor with the adhesion of matrix；The heating of surface overlaying
Temperature is higher, easily produces thermal stress and deformation, and surface forming performance is poor.Pricker coating and mother metal system metallurgical binding, bond strength ratio
The mechanical bond of thermal spraying is much higher, simultaneously pricker be coated with than built-up welding time heating-up temperature low, thermal stress and the change of mother metal performance
Less, and pricker coating surface is smooth, construction precision is high, i.e. can reach permissible accuracy through too small amount of processing.
Current pricker is coated with material and is made up of two parts: a part is brazing filler metal alloy, and its fusion temperature is relatively low, is generally called eutectic
Point component；Another part is the hard alloy that fusing point is high, is generally called high melting point component.Traditional pricker is coated with material and is typically powdery pricker
The pulp-like pricker that material, hard alloy particle, bonding agent, Organic substance etc. are prepared as suspending is coated with material or lamellar pricker is coated with material, then
Coat or be bonded at surface of the work, for preventing mother metal, the oxidation of powdered filler metal and promoting that solder is on hard alloy particle, mother metal surface
Wetting and spreading, pricker generally requires and constantly adds brazing flux during being coated with, inefficiency and easily cause a large amount of wastes of brazing flux,
Relatively costly.And powdered filler metal oxygen content is higher, during pricker is coated with, Organic substance is easily generated carbon residual, thus produces various gas
Hole, the pricker such as it is mingled with and is coated with defect.
Summary of the invention
It is an object of the invention to provide one and carry brazing flux, solder cleanliness factor height, brazing filler metal alloy and hard alloy particle
The compound pricker that ratio is consistent is coated with material, and the present invention also provides for this compound pricker and is coated with the preparation method of material.
For achieving the above object, the present invention can take following technical proposals:
Compound pricker of the present invention is coated with material, including being made up of hard alloy coating, brazing filler metal alloy layer and brazing flux coating successively
The banding of three-decker or tabular pricker be coated with material bodies.
The thickness of described hard alloy coating is 0.001 ~ 20mm, and the thickness of described brazing filler metal alloy layer is 0.001 ~ 20mm,
The thickness of described brazing flux coating is 0.001 ~ 20mm.
Hard alloy particle in described hard alloy coating is the one in carbide, nitride, boride, oxide
Or it is multiple.
Described brazing filler metal alloy layer uses the one in fine copper, cuprio, money base, manganio, palladio, titanium based solder.
Brazing flux in described brazing flux coating is corresponding general brazing flux.
The preparation method that the present invention is combined pricker painting material is as follows:
By thickness rolling brazing filler metal alloy band or the plate of design, hard alloy particle is sprayed to brazing filler metal alloy band in cold spraying mode
Or the upper surface of plate, brazing flux is sprayed in the way of thermal spraying the lower surface of brazing filler metal alloy band or plate the most again, makes certain
The compound pricker being made up of hard alloy coating, brazing filler metal alloy layer and brazing flux coating of size is coated with material.
Relative to the conventional suspension pulp-like pricker being prepared as by powdered filler metal, hard alloy particle, bonding agent, Organic substance etc.
Being coated with material or lamellar pricker and be coated with material, advantages of the present invention may be embodied in the following aspects:
1, during the compound pricker of the present invention is coated with material, brazing filler metal alloy and hard alloy particle ratio are consistent, and pricker can be effectively during being coated with
Ensure that pricker is coated with the stable, consistent of quality；
2, the compound pricker of the present invention carries brazing flux (brazing flux coating) in being coated with material, and pricker achieves the quantitative, certainly of brazing flux during being coated with
Moving and add, and brazing flux uses thermal spraying mode to be deposited on brazing filler metal alloy surface, brazing flux is firmly combined with brazing filler metal alloy.
3, during the compound pricker of the present invention is coated with material, brazing filler metal alloy layer compares the cleanliness factor height of powdered filler metal, can avoid pricker coating
Surface produces pricker painting defects such as being mingled with；
4, without Organic substance during the compound pricker of the present invention is coated with material, vacuum pricker can realize during being coated with remaining without charcoal, thus avoids
Pore, the pricker such as it is mingled with and is coated with the generation of defect；
5, the preparation technology of the present invention is simple, and formability is good, it is simple to deposits, transport and uses.
