Description
Technical field
The present invention relates to metal surface treatment technology, especially relate to a kind of Surface hardened layer pricker and be coated with material, the present invention is also
Relate to this 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.The pricker coating of pricker coating and mother metal system metallurgical binding, knot
The mechanical bond closing strength ratio thermal spraying is much higher；Pricker be coated with than built-up welding time heating-up temperature low, thermal stress and mother metal performance
Change less；Pricker coating surface is smooth, and construction precision is high, i.e. can reach permissible accuracy through too small amount of processing.
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 low melting point group
Point；Another part is the hard alloy that fusing point is high, is generally called high melting point component.Traditional Surface hardened layer pricker is coated with material and typically will
The pulp-like pricker that powdered filler metal, hard alloy particle, bonding agent, Organic substance etc. are prepared as suspending is coated with material or lamellar pricker is coated with material
Material, is then coated with or is bonded at surface of the work, is then placed in vacuum drying oven completing whole pricker and is coated with process.Powdered filler metal oxygen content is relatively
Height, and pricker be coated with during Organic substance be easily generated carbon residual, thus produce various pore, the pricker such as be mingled with and be coated with defect.
Summary of the invention
The Surface hardened layer pricker that it is an object of the invention to provide that a kind of solder cleanliness factor is high, will not produce pricker and be coated with defect is coated with
Material, the present invention also provides for this pricker and is coated with the preparation method of material.
For achieving the above object, the present invention can take following technical proposals:
Surface hardened layer pricker of the present invention is coated with material, is coated with material bodies including pricker, and it is by brazing filler metal alloy that described pricker is coated with material bodies
Internal layer and the hard alloy coating composition being sprayed on described brazing filler metal alloy internal layer.
The thickness of described brazing filler metal alloy internal layer is 0.001～20mm, the thickness of described hard alloy coating be 0.001～
20mm.Particulate material granularity in hard alloy coating is 15～45 μm.
Described hard alloy coating includes one or more in carbide, nitride, boride, oxide.
Described brazing filler metal alloy internal layer is the one in fine copper, cuprio, money base, manganio, palladio, titanium based solder.
The preparation method that Surface hardened layer pricker of the present invention is coated with material is as follows:
First brazing filler metal alloy is smelting, extruding, rolling process are prepared as in the banding that is of the required size or tabular brazing filler metal alloy
Layer, then sprays to brazing filler metal alloy inner layer sheet by satisfactory for the granularity processed cemented carbide powder by cold spray apparatus
Face, forms certain thickness hard alloy coating.
It is an advantage of the current invention that simple in construction, vacuum pricker is coated with effective, concrete:
It is coated with material with the conventional suspension pulp-like vacuum pricker being prepared as by powdered filler metal, hard alloy particle, binding agent, Organic substance etc.
Material or lamellar vacuum pricker are coated with material and compare, and the pricker of the present invention is coated with material and is easy to deposit, transport and use；Brazing filler metal alloy is with hard simultaneously
Matter alloy ratio is consistent, and pricker can be coated with the stable, consistent of quality by effective guarantee pricker during being coated with；Owing to brazing filler metal alloy layer is than powdery pricker
Material cleanliness factor is high, pricker coating surface can be avoided to produce and be mingled with, and pricker is coated with in material without Organic substance, and pricker can realize without charcoal during being coated with
Residual, thus avoid pricker coating and produce pore, the defect such as be mingled with.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of the present invention.
Detailed description of the invention
As it is shown in figure 1, Surface hardened layer pricker of the present invention is coated with material, being coated with material bodies including pricker, pricker is coated with material bodies and is
Be made up of brazing filler metal alloy internal layer 1 and the hard alloy coating 2 being sprayed on brazing filler metal alloy internal layer 1, in hard alloy coating 2
Pellet sizes is 15～45 μm.
During making, the thickness of brazing filler metal alloy internal layer 1 and hard alloy coating 2 can adjust in the range of 0.001～20mm:

With the life-span, it usually needs be coated with hard alloy layer at coal cutting pick front-end surface pricker, to improve its hardness and wearability, extend coal cutting pick
Service life, now, brazing filler metal alloy internal layer 1 used and the thickness of hard alloy coating 2 are typically between 0.1～1mm.
Vinyon compressor granulating template surface is owing to constantly being swiped by four cutting knifes rotated, and working condition is disliked
Bad, it usually needs at template surface pricker hard coated layer matter alloy coat, now brazing filler metal alloy internal layer 1 used and hard alloy coating
The thickness of 2 is typically between 1～4mm.
Hard alloy coating steel plate is to specialize in the plate product that large area wear working condition uses, and is fine in toughness, plasticity
Ordinary low-carbon steel or surface of low-alloy steel pricker hard coated layer matter alloy, at this moment, brazing filler metal alloy internal layer 1 used and hard alloy
