Description
The present invention relates to a kind of iron-based composite deposite brush plating liquid.
Use electric plating method, make solia particle and iron codeposition on negative electrode in the plating iron solution.Owing to the existence of these solia particles, can form the iron-based composite deposite of wear-resistant or antifriction.This composite deposite all is to adopt the method for groove plating to obtain both at home and abroad.Yet there are no the patent documentation report and obtain the iron-based composite deposite with the method for brush plating.All use brush plating nickel, chromium, tungsten cobalt and alloy thereof as wear resistant coating at present, use the brush plating pasture as ware reducing coating layer.The microhardness of nickel, chromium, tungsten, cobalt and alloy layer thereof can reach 600, but their cost height, pollute big.And the microhardness of the pure iron base in the iron-based composite deposite just can reach 700, and the microhardness of superabrasive particle therebetween can reach 2000.Its abrasion resistance substantially exceeds above these alloy layers.In addition, iron-based composite deposite cost is low, pollution is few.Especially the cost of iron-molybdenumdisulphide antifriction composite deposite is lower, and its cost is 1% of an indium coating, and therefore expert both domestic and external is devoted to the research of iron-based composite deposite.The plating bath of electroplating iron composite deposite is well-known in coating bath.But handiness, the maneuvering ability of groove plating are poor.It can not plate big and the special workpiece of shape.Brush plating then has very big handiness, maneuvering ability.In order to satisfy the different shape workpiece, especially big and workpiece that shape is special is necessary to develop the plating bath of brush iron base composite cladding to wear-resistant and requirement antifriction.The very easily oxidation of plating bath of existing groove plating iron base composite cladding, the incompatibility brush-plating technique is with the requirement of plating with usefulness; During brush plating,, cause the solia particle in the iron-based composite deposite to be significantly less than the iron-based composite deposite that the groove plating is obtained in addition because the relative movement between workpiece and the brush is difficult to and the iron codeposition solia particle.Therefore, the inventor is for solving above-mentioned two technological difficulties, and the spy develops the plating bath of the iron-based composite deposite that is suitable for brush-plating technique.The key problem in technology of this invention is: add buffer reagent and make plating bath anti-oxidant in the plating bath of iron-based composite deposite, add the solia particle dispersion agent and make the easy and iron codeposition of solia particle, add reductive agent and make plating bath energy long-term storage.When so just having solved the easy oxidation of plating bath of iron-based composite deposite and brush plating, the problem of solia particle and iron codeposition difficulty.
The plating bath of brush iron base composite cladding is made up of molysite, solia particle and sodium-acetate, sodium metnylene bis-naphthalene sulfonate, sea-gull washing composition (surfactant composition that contains coconut oil alkyl diethanolamide) or white cat liquid detergent (Shanghai Synthetic Detergents Factory's product) and water.Said solia particle can be the solid lubricant that makes the wear-resistant superabrasive particle of coating or make the coating antifriction.
The plating bath of this brush iron base complex coating has two classes.One class is the iron-based composite deposite plating bath that makes coating wear-resistant, and its iron plating liquid is ferrous sulfate or iron protochloride, and making the wear-resistant superabrasive particle of coating is aluminium sesquioxide, silicon carbide, wolfram varbide, silicon-dioxide etc.Other adds sodium-acetate, sodium metnylene bis-naphthalene sulfonate, sea-gull washing composition or white cat liquid detergent, and all the other are water.Another kind of is the iron-based composite plating bath that makes the coating antifriction, molysite wherein is ferrous sulfate or iron protochloride, the solid lubricant that makes the coating antifriction is molybdenumdisulphide, graphite, mica etc., other adds sodium-acetate, sodium metnylene bis-naphthalene sulfonate, sea-gull washing composition or white cat liquid detergent, and all the other are water and ethanol.
Two optimum formulas are arranged in the plating bath of this brush iron base composite cladding.The plating bath of first iron-based-aluminium sesquioxide compound wear resistant coating.Its optimum formula is, ferrous sulfate 340 grams per liters, and sodium-acetate 20 grams per liters, aluminium sesquioxide 100 grams per liters (particle diameter is 5～10 microns), sodium metnylene bis-naphthalene sulfonate 0.1 grams per liter, sea-gull washing composition or white cat liquid detergent number droplet, all the other are water.The compound method of this liquid is, with magnetized distilled water ferrous sulfate and sodium-acetate are dissolved respectively, take out the part of sulfuric acid ferrous iron solution aluminium sesquioxide is soaked into activation, add sodium metnylene bis-naphthalene sulfonate again and carry out agitation as appropriate, aluminium sesquioxide is disperseed, make the plating bath of aequum by said ratio, the acidity of sulphuric acid soln control plating bath of using 1: 1 at last is in the scope of PH=1.5-2.This solution is now with the currently general.The plating pre-treatment of brush plating plating piece is identical with general brush plating.The temperature of brush plating is controlled at 30 ℃, and initial voltage reaches 10 volts.With the pure iron layer is the end, increases the content of aluminium sesquioxide later on gradually.Electric current can increase along with the time of lining and increase during brush plating, and maximum current density allows at 100A/dm
2, must be provided with sufficient plating bath this moment.Speed of relative movement between control brush and the workpiece be 10-15 rice/minute.Can make anode plating pen with graphite or iron, the latter is a soluble anode, allow bigger current density to carry out brush plating, and plating bath is difficult for oxidation.During operation, the contact pressure between workpiece surface and the brush is little, even can flow plating, and more solia particle deposition can be arranged like this.After 0.1 millimeter of coating arrival safe thickness, sedimentation velocity descends, and plating can only reach polishing action, and this moment, contact pressure can be greater than 12 gram per centimeters
2, to increase the surface smoothness of coating.
It two is iron-molybdenumdisulphide antifriction composite deposite plating baths, and its optimum formula is ferrous sulfate 340 grams per liters, sodium-acetate 20 grams per liters, molybdenumdisulphide 40 grams per liters, sodium metnylene bis-naphthalene sulfonate 0.1 grams per liter, sea-gull washing composition or white cat liquid detergent number droplet, all the other are water and ethanol.The compound method of this liquid is, by said ratio, after with distilled water ferrous sulfate and sodium-acetate being dissolved respectively, slowly mix, molybdenumdisulphide is suspended in the second alcohol and water, add sodium metnylene bis-naphthalene sulfonate and pulverize and stir, treat homodisperse after, could blend together iron-molybdenum disulfide composite plating layer plating bath with plating bath.The shelf-time of this plating bath is longer.30 ℃ of room temperatures are opened wide to place and still can be used in two days.Its brush-plating technique is identical with the brush-plating technique of iron-aluminium sesquioxide composite deposite plating bath.But in order to obtain the last smooth finish of coating, the molybdenumdisulphide content in the plating bath will suitably increase, and the contact pressure of workpiece and brush is little, even reaches stream plating degree.
The plating bath of two class brush iron base composite claddings of the present invention can be used according to the requirement of workpiece, also can separately use.The plating bath compound method of this brush iron base composite cladding is simple, easy to operate.Use this plating bath brush plating cost low, pollute for a short time, deposition is fast.For example, during 30 ℃ of room temperatures, the plating bath of brush iron-aluminium sesquioxide composite deposite, deposit thickness was 0.17 millimeter in 30 minutes.The plating bath of brush iron-molybdenum disulfide composite plating layer, deposit thickness was 0.1 millimeter in 30 minutes.In addition, the fastness to wear of the wear-resistant composite deposite of brush iron-aluminium sesquioxide is identical with the wear-resistant composite deposite of groove plating iron-aluminium sesquioxide, and when the multiple coating of the iron of institute's brush plating-molybdenumdisulphide antifriction group was paid mill with pairing, frictional coefficient was minimum, and it is little that wearing and tearing are paid in pairing.For example when iron-molybdenumdisulphide antifriction composite deposite and copper alloy axle during to mill, uses and do not have wearing and tearing in 1 year, the machine tool guideway made from nickel cobalt oxidation aluminium does not have wearing and tearing half a year to the use of grinding machine bed guide rail; The cylinder made from clean steel under the oil-free lubricatoin condition, is made the application of load wear test when rubbing, and cylinder does not have wearing and tearing and copper surface, and more mill is more smooth.Utilize this plating bath brush plating, can be made into the composite deposite of the wear-resistant or antifriction of various required iron-baseds.The plating bath of this brush iron base composite cladding has very big adaptability and versatility.It can repair with iron and steel or non-ferrous metal is the wearing part that starting material process the different shape workpiece, also can increase the ability of the wear-resistant and antifriction of new workpiece.Prolong workpiece work-ing life, save starting material.
Repair the stereotype roller bearing end of LS-201 printing turbine in October, 84.Repairing size length is 150 millimeters, 0.7 millimeter of diametric(al).Plate one deck nickel earlier, the thicker 0.08 millimeter iron-aluminium sesquioxide composite deposite of brush plating, the thick 0.025 millimeter iron-molybdenum disulfide composite plating layer of brush plating at last.Plating Bi Weijing break-in uses of promptly installing, continuous two classes of runnings did not have wearing and tearing in 1 year, and the stereotype roller radial tolerance reaches within 0.06 millimeter, is the tolerance zone that this machine design allows, and running is steady, and functional, printing quality reaches technical requirements.
