Description
The present invention relates to a kind of method of metal component surface intensive treatment, especially be related to the method for high anti-corrosion, resistance wear-resistance oil pump surface Hardening Treatment.
At present, the oil well pump that China uses in the oil field mainly is made up of pump barrel, plunger, valve ball and valve seat.Containing the medium-term and long-term work of many corrosive mediums such as hydrogen sulfide, carbonic acid gas, acid, alkali, salt, bacterium for adapting to, anti-corrosion and wear-resisting measure adopts expensive Langaloy steel system pump more; Or methods such as its chrome-faced, boronising, carburizing, nitrogenize or nitrogen boron co-diffusion are solved.But because of the effect of strong erosion, strong mill, its effect is short in tens days, how just need change with some months.Like this, influence oil pump capacity, increase productive expense, it is multiple more particularly to be lost difficulty that the pump that ground abandons, and reality is not ideal.
The object of the present invention is to provide a kind of method for surface hardening that can make oil well pump reach high anti-corrosion, high abrasion.
The object of the present invention is achieved like this: promptly to the main oil well pump of being made up of pump barrel, plunger, valve ball, valve seat and auxiliary thereof, the principle of work by laser quenching, surfacing remelting and electroless plating imposes surface Hardening Treatment.Wherein:
Pump barrel (9) internal surface is executed laser surface hardening earlier handle, adopt chemical plating method that nickel-base alloy ion chromium is combined on the surfaces externally and internally again;
Plunger (6) surface is utilized the surfacing remelting method, the melting welding of nickel chromium triangle borosilicate self-fluxing alloy powder on it, is adopted chemical plating method more on this basis, nickel-base alloy ion chromium is combined on the position of surfacing not;
Working face to valve seat (4.12) utilizes plasma spray welding method, will be through Zirconium dioxide powder melting welding that yttrium superoxide is handled on it, again through laser remolten and overall chemical plating lid;
To other auxiliary surface, adopt chemical plating method that nickel-base alloy ion chromium is closed on it.
Chemical plating method is mainly to be dissolved with nickel and phosphonium ion in the solution, and both mass ratioes are 87-91: 13-9, and working temperature is 85 ℃～91 ℃, and plating piece within it can unidirectional revolution or non-unidirectional revolution circulation, adjusts thickness of coating according to immersion plating time length.
Surfacing, remelting method are by a kind of special-purpose soldering set, are that the chromium of 15-16, the boron of 2.9-3.1, the silicon of 1.9-2.1, the nickel self-fluxing alloy powder of surplus are welding on the workpiece surface with mass ratio.
Thereby realized that on the basis of conventional pump structure overall performance has reached surfaces externally and internally to be strengthened and antiseptic purpose.

Further explain below in conjunction with accompanying drawing:
Pump barrel and plunger are that a pair of height is anti-corrosion, the high abrasion fastness, for making them reach the purpose of high anti-corrosion, high abrasion, impose laser quenching earlier and handle add pump barrel internal surface with degreasing and rust removal through machine, what connect carries out honing, surfaces externally and internally to it utilizes chemical plating method again, and different metal ion chromium such as nickel phosphorus, nickel boron, nickel chromium triangle, nickel tungsten or NiTi are combined on the workpiece surface.Wherein, nickel phosphorus mass ratio is 87-91: 13-9, and optimum value is 89: 11, and the plating bath working temperature is 85 ℃～91 ℃.Optimum value is 88 ℃, and plating speed is 10-15um/h, is controlled at usually 5-7 hour, and temperature is handled in imposing at last, as Fig. 2.
To through machine add, sandblast and give thermal treatment after plunger surface, adopt two one step process of surfacing and remelting, with nickel chromium triangle borosilicate self-fluxing alloy powder, by the high-speed flame spray gun, functional quality under 940 ℃ to the 1170 ℃ conditions than nickel self-fluxing alloy powder melting welding for the silicon of the boron of the chromium of 15-16,2.9-3.1,1.9-2.1, surplus on, behind the mill of surface, cover processing in carrying out electroless plating, as Fig. 3.
To through machine add with degreasing and rust removal after valve seat, its working face is by the high-performance plasma spray gun, will be on the Zirconium dioxide powder surfacing that yttrium oxide is handled, impose laser remolten again, be intended to form a kind of wear-resisting working face, be the further resistance to abrasion against corrosion that improves it, carry out the electroless plating covering again behind finish turning and the outer mill and handle, as Fig. 4.
The present invention has following advantage compared to existing technology:
1, because the pump barrel inner surface is processed through a laser quenching, carries out chemical plating at surfaces externally and internally again and cover processing, make the erosion resistance of pump barrel exceed several times to tens times of 1Cr18Ni9Ti; Hardness is brought up to more than the HV550 to 750; Be up to HV1100; Coating and substrate combinating strength are good, as with the medium carbon steel bond strength at 30Kgf/cm2More than; Coefficient of friction is little, can be low to moderate below 1/2nd of steel.
2, because plunger and valve seat working face, carry out earlier surfacing and process, impose again chemical plating and cover, make their working surface melting welding layers and coating dense structure, bond strength height, having height anti-corrosion, high-wear resistance, particularly valve seat can be with 45＃Steel replaces traditional GCr15 bearing steel or high carbon chromium stainless steel to make, and makes its cost, and the characteristics of tool shock resistance, good seal, thereby prolongs in anticorrosion, wear-resisting, service life.
3, owing to all made chemical plating for other auxiliary surface of pump and cover to process, so totally wear-resistant, corrosion resistance, the corrosion resistant performance of pump are greatly improved, some disadvantages of present anticorrosion, wear-resistant surface processing method have been overcome.
