The plating solution comprises, 80-84 g/L of sodium tungstate, 6-10 g/L of sodium molybdate, 14-18 g/L of nickel sulfate, 34-38 g/L of boric acid, 30-36 g/L of sodium sulfate, 20-24 g/L of ammonium sulfate, 30-34 g/L of tartaric acid, 11-15 g/L of potassium pyrophosphate, 10-14 g/L of ascorbic acid, 1-3 ml/L of formaldehyde, 2-4 ml/L of dimethyl hexynol, and the balance being water.

Description

A kind of plating solution of pumping components electroplating surface tungsten nickel alloy coating
Technical field
The present invention relates to electroplating technology field, particularly relate to a kind of plating solution of pumping components electroplating surface tungsten nickel alloy coating.
Background technology
Sucker rod and oil pick-up tube are the oil recoveries for oil field.Mining site runs into a difficult problem for two big world levels: corrosion and wearing and tearing.Often containing CO in well liquid 2, H 2the corrosive medium such as S and salt solution, causes sucker rod fatigue corrosion fracture, oil well pump and spiral pump corrosion failure, and tube corrosion is bored a hole, and has a strong impact on crude production.Some well on the beams of Dongxing oil fields in Shengli, just rupture because corrosion box cupling (45 steel, modifier treatment) works for three months.Some well on the beams of Zhongyuan Oil Field, just there is fatigue corrosion fracture in three months in sucker rod work.In inclined shaft (especially hole structure is the oil well of dog-leg shape), sucker rod and oil pipe generation eccentric wear, usually grind off the bar head of the wall of box cupling, sucker rod or the some of the body of rod, leaked by oil pipe grinding.
In oil well pump, plunger and pump barrel are friction pairs, and in spiral pump, stators and rotators is friction pair.In oil pumping process, the well liquid containing sand grains exists in the surface in contact of these two kinds of friction pairs, accelerates wearing and tearing.According to filed application experience, the damage of sucker rod, oil well pump and oil pipe, because corrosion and the damage caused of wearing and tearing account for more than 70%.Over more than 100 year, the researchist of oil recovery machiner has carried out many research work for corrosion and wear problem, and on sucker rod, as adopted corrosion resisting alloy: such as K grade pumping rod adopts 20Ni2Mo, this corrosion resisting alloy containing Ni, Cr, Mo is more expensive; Adopt corrosion protection coating: comprise metallic coating (such as heat invades aluminium, chromium plating, spraying nickel-base alloy) and non-metallic coating (such as epoxy coating), Problems existing: coating shedding, this sucker rod can not be used for inclined shaft; Adopt nonmetal: glass fiber reinforced plastic oil pumping rod, Carbon Fiber Reinforced Plastic Continuous Sucker Rod, these two kinds of sucker rods are somewhat expensive, resistance to compression and wear resisting property poor; Adopt inhibiter: somewhat expensive, preservative effect is undesirable; In oil pick-up tube, adopt nickel phosphorus Composite Coatings undercoat technology; Bimetal oil pipe; Nitriding; Frp lining oil pipe.Though achieve certain achievement, but problem does not also solve.
Summary of the invention
The object of the invention is to the plating solution proposing a kind of pumping components electroplating surface tungsten nickel alloy coating, coating prepared by this plating solution is the alloy layer that the one deck formed at pumping components is made up of tungsten, molybdenum, nickel, this alloy layer hardness is high, and wear resistance is good, and high with basal body binding force.
For reaching this object, the present invention by the following technical solutions:
A plating solution for pumping components electroplating surface tungsten nickel alloy coating, this plating solution consists of: sodium wolframate 80-84g/L, Sodium orthomolybdate 6-10g/L, single nickel salt 14-18g/L, boric acid 34-38g/L, sodium sulfate 30-36g/L, ammonium sulfate 20-24g/L, tartrate 30-34g/L, potassium pyrophosphate 11-15g/L, xitix 10-14g/L, formaldehyde 1-3ml/L, dimethylated hexynol 2-4ml/L, surplus is water.
Preferably, this plating solution consists of: sodium wolframate 82g/L, Sodium orthomolybdate 8g/L, single nickel salt 16g/L, boric acid 36g/L, sodium sulfate 33g/L, ammonium sulfate 22g/L, tartrate 32g/L, potassium pyrophosphate 13g/L, xitix 12g/L, formaldehyde 2ml/L, dimethylated hexynol 3ml/L, surplus is water.
The present invention has following beneficial effect:
The present invention adopts the alloy of nickel, molybdenum, tungsten three kinds of elements, and overcome the defect of single-element or wherein two kinds of elements, the coating surface of preparation is non-microcracked, has well corrosion-resistant and rub resistance, and coating is combined with matrix well; Various chemical reagent is little to environmental hazard, process stabilizing, the simple and convenient operation of bath composition.Coating of the prior art can be substituted.
