Description
Technical field
The invention belongs to engineering goods manufacturing technology field, more particularly, is related to TC bearings and its manufacture method.
Background technology
Hard alloy (TC) journal bearing, is that, using high temperature furnace sintering process method, it is by carcass and hard alloy Jing prickers
Welding is manufactured, and is formed by machining.TC bearings are the key fitments of the helicoid hydraulic motor of oil exploitation, existing
TC bearings adopt tungsten-cobalt series hard metal for the strengthening material on surface, as tungsten-cobalt series hard metal shrinkage factor is steel body
30% or so, very big internal stress influence using effect can be produced in brazing process, thus solder select need using modeling
The good copper base brazing material of property.Copper base solder has many unfavorable factors, and copper base solder first mostly is bulk, it is impossible to put
Put between steel body and hard alloy layer, existing preparation method as shown in figure 1, steel body (i.e. bearing body,
It is generally cylindric) external peripheral surface on be coaxially disposed hard alloy layer, folder is provided on the outside of hard alloy layer
Tight steel sheath, arranges the cuprio pricker of bulk in the upper end of hard alloy layer and between the good steel sheath of steel body
Material, then carries out soldering so that copper base solder relies on gravity with top-down flowing aggressive forms under normality air atmosphere
Into between steel body and hard alloy layer, to form brazing layer bonding steel body and hard alloy layer, finally in car
The part for removing steel sheath and steel body upper end setting copper base solder is processed on the processing equipments such as bed, that is, obtains table
Face arranges the steel body (i.e. TC bearings) of hard alloy layer.The process of infiltration of flowing in this preparation method cannot be entered
Row monitoring, is often by virtue of experience judged in preparation, it is impossible to ensure copper base solder complete wetting steel body and hard
Surface (i.e. lack of fill-out) between alloy-layer, the copper base brazing strength of materials is low in addition, and causing current TC bearings makes
With during, hard alloy comes off, and can produce the hard alloy for coming off and close with the hard for not yet coming off after hard alloy comes off
Effect between gold, causes the non-serviceable phenomenon of whole workpiece, reduces service life, the use of current TC bearings
Life-span is less than 200 hours；The corrosion resistance of copper base solder is poor again, and in oil drilling operation, soldering often occurs in Jing
Hard alloy blocks obscission caused by material corrosion.For the problems referred to above, current solution has (1) by virtue of experience
Carry out repeatedly melt down soldering, to reach the purpose of abundant infiltration；(2) Jing tests obtain the use longevity of TC bearing samples
Life, was changed before service life is reached, to avoid coming off for hard alloy.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, in order to solve solder from lack of fill-out, soldering strength is too low,
The problem of corrosion resistance difference, proposes that a kind of employing steel bonded carbide coordinates the TC for carrying out vacuum brazing with Ni-based paste solder
The process of preparing of bearing.

TC bearings and its manufacture method, being coordinated with Ni-based paste solder using steel bonded carbide on steel body surface is carried out
The process of vacuum brazing, to form steel bonded carbide layer on steel body surface using brazing layer, wherein in soldering
The metal of layer both sides produces metallurgical binding with brazing layer.
The manufacture method of TC bearings, arranges nickel-based solder layer, between steel body and steel bonded carbide to form entirety
Part to be brazed, then arranges steel sheath outside overall part to be brazed, overall part to be brazed is protected, most
Carry out soldering afterwards under vacuum, brazing temperature is between 900-1100 degree Celsius.
In above-mentioned technical proposal, steel body is TC bearing bodies, according to the use requirement of TC bearings, from high-quality
Bearing steel such as GCr15,42CrMo.
In above-mentioned technical proposal, steel sheath selects the conventional outermost layer protection materials of TC field of bearings, for example
Q235 steel.
In above-mentioned technical proposal, selection carries out soldering under vacuum, (is not passed through indifferent gas using Raise vacuum degree
Body) method, to avoid the impact of oxygen in air, nitrogen, hydrogen and noble gases, the order of magnitude of the vacuum for 0.01Pa
(i.e. the minimum order of magnitude of vacuum is 10 above-2Pa), select 0.005-0.02Pa.
In above-mentioned technical proposal, steel bonded carbide for TiC systems steel bonded carbide, such as trade mark GT35, R5,
The steel bonded carbide of D1, T1, TM60.
In above-mentioned technical proposal, nickel-based solder layer is made up of, Ni-based pricker Nickel-based brazing material (i.e. Ni-based paste solder)
Wlding material is integrally presented paste, is made up of nickel base powder and binding agent, and the mass ratio of nickel base powder and binding agent is (5-10)：
1, preferably (7-9)：1, wherein：
Binding agent is positive certain herbaceous plants with big flowers alcohol, vaseline or alginate jelly；In nickel base powder, the mass percent of each alloying element is as follows：

It is remaining for nickel；The oxygen content of nickel base powder is not more than 300ppm.
In nickel base powder, the mass percent of each alloying element is preferably as follows：Carbon is 0.4-0.8%；Silicon is 3-4%；Boron is
1.5-2.5%；Chromium is 15-20%；Ferrum is 5-12%；Phosphorus is 1-2%；Remaining as nickel；The comprehensive oxygen content of nickel base powder is excellent
Select 100-200ppm；The granularity of nickel base powder is between 100 to 250 mesh.
In above-mentioned technical proposal, the thickness of nickel-based solder layer is grade or Centimeter Level, such as 0.1-0.5mm；1
—3cm。
In above-mentioned technical proposal, application of the above-mentioned Nickel-based brazing material in TC bearings are prepared.
In above-mentioned technical proposal, from room temperature, 20-25 degrees Celsius carry out being warming up to brazing temperature, and programming rate is per minute
5-10 degrees Celsius, it is incubated in brazing temperature, then temperature retention time at least 30min naturally cools to room temperature with stove,
Temperature retention time preferably 30-60min.
As Nickel-based brazing material is integrally presented paste and shows as viscosity, between steel body and steel bonded carbide layer
When being configured, it is contemplated that Nickel-based brazing material is smeared on the circumferential outer surface of steel body to form nickel-based solder layer first,
Steel bonded carbide layer is set on nickel-based solder layer, or Nickel-based brazing material is smeared on steel bonded carbide layer with shape
Into nickel-based solder layer, then by nickel-based solder layer with carry out on the circumferential outer surface of steel body it is bonding.
Typically with the matrix of steel, steel can account for the 50%～70% of alloy gross weight to the steel bonded carbide that the present invention is used, wherein
Its hard phase is tungsten carbide or titanium carbide etc..At the same time, for compared with ordinary rigid alloy, its toughness index is also obtained
Larger improvement.A kind of comprehensive typical organization, that is, tempered martensite after quenching and tempering, can obtained particularly
