Description
Technical field
The present invention relates to a kind of preparation methods of bar base part surface abrasion resistance anti-corrosion layer, and in particular to a kind of to use superelevation
The method that rate laser cladding prepares sucker rod, belongs to technical field of surface.
Background technology
Sucker rod is suitable for the oil recovery in oil field, is the important component in oil pumping system, plays connection pumping unit and pumping
The effect of oil pump and passing power.The exploitation in oil field at present has been enter into high water-cut stage, and the salinity of Produced Liquid is high, contains in well liquid
The corrosive mediums such as CO2, H2S, brine.It is taken in well liquid medium using the sucker rod that Fine Steel Casting iron or steel alloy are produced as raw material
During labour, due to the double action of chemical attack and electrochemical corrosion, leads to the heavy corrosion of sucker rod, in turn result in oil well
Failure.And since sucker rod inevitably rubs with oil pipe in operation, sucker rod surface has been further exacerbated by it
Damage.It is damaged caused by corroding and wearing according to filed application experience, in the damage of sucker rod and accounts for 80% or more.
So far, related researcher expands many researchs, main corrosion-resistant mill for corrosion and wear problem
There are three ways to damage：Corrosion inhibiter, plating and laser melting coating is added.
（1）Corrosion inhibiter is added.Corrosion inhibiter can be formed with a kind of protective film of densification on sucker rod surface, be sucker rod sheet
Body is kept apart with corrosive medium, achievees the purpose that protect sucker rod, the protective film of formation that can also play eccentric wear certain prevention
Effect.But corrosion inhibiter will be selected according to Corrosion Types and corrosive medium, and the Corrosion Types of actual condition and corrosive medium
It is very complicated, and the wearability of protective film is very poor, therefore protective effect unobvious.
（2）Electroplating technology.Domestic the most widely used method is electroplating technology at present, and this method is simple for process at low cost
It is honest and clean.But coating is physical bond with matrix, broken rubbing for a long time, easily occurring coating under the working condition of corrosion in conjunction with force difference
It is broken, peel off the phenomenon that.Seriously affect protecting effect.
（3）Laser melting and coating technique.The feature that this method is concentrated based on laser energy, energy density distribution is uniform, it is defeated in heat
Enter and form the Ni-based coating of even compact in matrix surface under conditions of amount very little, coating is metallurgical binding state with matrix, is kept away
The generation of hole crackle is exempted from, to thoroughly obstruct contact of the corrosive medium with matrix.But traditional laser melting coating rate compared with
It is low, and coating roughness is larger after cladding, it is also necessary to such as turning mechanical processing ensures part dimension accuracy, therefore produces effect
Rate is low.Simultaneously in order to prepare Large area coatings faster, traditional laser cladding method uses raising laser power and increase
The method of facula area, but excessively high power can improve the temperature gradient of sucker rod, cause to deform after processing.
Invention content
The present invention is adopted for conventional laser cladding method cladding rate is low, the low problem of coating surface flatness after cladding
With coaxial powder-feeding formula laser melting coating mode, by accurately controlling powder convergent point (amyloid plaque) and laser spot（Hot spot）Position,
It realizes superelevation rate laser melting coating, and ensures coating surface flatness after cladding.It should be noted that the ultrahigh speed in the present invention
It is for existing laser melting coating speed, which specifically refers to laser scanning linear velocity and be more than or equal to 20m/
min。
The particular content of technical solution of the present invention is：
The sucker rod includes the coating of sucker rod matrix and cladding on the matrix.The step of this method is：
（1）To nickel base powder screening and purified treatment, the powder that particle size range is more than 90% for 15~50 μm, sphericity is obtained, so
Afterwards by 120~150 DEG C of holding temperature, 1.5~3.5h of soaking time drying and processing after vacuum preservation, it is spare.
（2）The technological parameter of superelevation rate laser melting coating is set, concrete technology is：Spot diameter is 1~3mm, sucker rod
Linear resonance surface velocity, that is, cladding rate is 20~100m/min, and 0.2~0.4mm of feed of every rotation, laser power is 900~1600W,
Powder feeding rate is 5~25g/min.
（3）Sucker rod matrix clamping by any surface finish zero defect, diameter less than 0.2~0.6mm of finished diameter is in numerical control
On the swing mechanism of equipment, and hot spot and amyloid plaque are adjusted with respect to the position above sucker rod matrix clad can fusion so that Ni-based powder
The molten bath that end instills matrix surface in droplets is combined with matrix.
（4）Using coaxial powder-feeding ultrahigh speed laser cladding method, step is used（2）The technique is by step（1）Gained
Nickel base powder cladding to column matrix surface, obtain the coating that thickness is 0.15~0.45mm.At this time column diameter be more than at
0.1~0.3mm of product diameter.
（5）It keeps column linear velocity, feed of every rotation and focal position of laser constant, laser power is reduced to
800~1500W carries out laser remolten under the conditions of not bothering to see me out powder to cladding coating, obtains smooth surface light, without pit and crackle
Coating.
The present invention is relative to the advantage of conventional laser cladding method：Cladding rate is high, can significantly improve production effect
Rate；Simultaneously because larger overlapping rate, the coating surface flatness after laser remolten is smooth higher than traditional cladding coating
Degree, further increases production efficiency and can reduce production cost；Most of energy of conventional laser cladding by Matrix absorption and
The energy of high rate laser cladding is largely absorbed by metal powder, therefore dilution rate is low, and coating composition is influenced by basis material
Smaller, while sucker rod substrate temperature gradient smaller, deflection smaller are conducive to subsequent assembly.
