Description
Technical field
The present invention relates to the metal material surface processing technology field, the solution of the chemical carbon removing of a kind of engine component at hot environment work (for example high-pressure turbine blade) carbon is provided especially.
Background technology
The working temperature of engine high pressure turbine blade is about 1000 ℃, under this high temperature and oxygenizement, the soot particles of the impurity in the fuel oil and insufficient generation of burning is deposited on matrix surface and along with the raising of temperature and the prolongation of working hour, further polycondensation becomes the colloidal mixt of bituminous matter, carboids and hydrocarbon matter, promptly so-called carbon distribution.
The carbon distribution major part is that the component by insoluble or indissoluble constitutes, and quality is hard, and adhere firmly is difficult to remove.Especially the carbon distribution of high-pressure turbine blade inner chamber, because the structure of inner chamber is special, narrow space, general mechanical means does not all have effect, and the difficulty of removing is just bigger.Usually the decarbonizing method mainly is infiltration, wetting, the solvency action by solvent molecule, makes carbon distribution by loose, reduces the sticking power between carbon distribution and the matrix, and by suitable external force effect, it is separated with matrix, reaches the purpose of removal.
Blade inner chamber foreign matter is the dark brown speckles shape, quality is harder, we can see that the content of oxygen the inner chamber foreign matter is the highest from table 1, non-metallic element mainly is oxygen and silicon, and gold bits element is with the ratio maximum of aluminium, contain multiple metallic elements such as calcium, magnesium, potassium, iron, nickel, titanium, chromium simultaneously, therefore in fact our said carbon distribution is the mixture that multiple metal oxide is formed.This blended metal oxide through secular hot operation state become gradually be close to the ceramic-like product and with the combustion chamber fuel oil in impurity and mixed deposits such as the soot particles of insufficient generation of burning, dust at matrix surface, and along with the raising and the prolongation of working hour of temperature progressively changes into harder hard scale, quality is very hard, like ceramic body, but fragility is bigger, and and matrix between certain bonding force is arranged.

Because carbon distribution is the sticking power strong solid dirt very that is deposited in densification together by multiple mixture, adopts ordinary organic solvents and inorganic solvent all to be difficult to remove.Usually the decarbonizing method mainly is infiltration, wetting, the solvency action by solvent molecule, makes carbon distribution by loose, reduces the sticking power between carbon distribution and the matrix, and by suitable external force effect, it is separated with matrix, reaches the purpose of removal.
Existing clean-out system 781 is a kind of based on tensio-active agent, and is relatively poor to effects such as more serious greasy dirt, carbon distributions.It mainly is by infiltration, wetting action to surface and oil contaminant, carbon distribution, reaches the greasy dirt of removal blade surface and the purpose of carbon distribution, and along with the prolongation that engine uses ruffian to order, carbon distribution (containing dirt) is more and more serious.Therefore this class has certain cleaning performance in conjunction with action of ultrasonic waves for general greasy dirt based on the clean-out system of tensio-active agent.Bad to producing the carbon distribution effect under engine high pressure turbine blade long term high temperature and the oxygenizement.
781 aqueous cleaning agents are a kind of tensio-active agents, and greasy dirt, carbon distribution etc. is not had solvency action, and it mainly is by infiltration, wetting action to surface and oil contaminant, carbon distribution, reach the greasy dirt of removal blade surface and the purpose of carbon distribution.Therefore class can only produce some effects based on the clean-out system of tensio-active agent to the greasy dirt dirt on high-pressure turbine blade surface in conjunction with action of ultrasonic waves, but for the high-pressure turbine blade inner chamber have the greasy dirt of certain sticking power dirty it almost without any effect.
For this reason, in order to improve the cleanup action of chemical water based cleaning agent, people expect to obtain a kind of performance and better are used for the solution of chemically removing carbon deposition on high-pressure turbine blade and use the solution of this better effects if to carry out the concrete operation method of chemically removing carbon deposition on high-pressure turbine blade.

Described EDTA-Na
2Be specially disodium EDTA; 781 is the aqueous cleaning agent that commercially available Shenyang City poplar official silicon sol factory produces, and its composition requires as follows: alkylol amide, trolamine, OP (polyvinyl alcohol octyl phenyl ether) emulsifying agent, and OP emulsifier content wherein is maximum, and trolamine takes second place.
It is the mixing solutions of forming with organic solvent, inorganic solubility promoter etc. that the special solution that is used for chemically removing carbon deposition on high-pressure turbine blade used in the present invention in fact also belongs to a kind of water-base cleaning liquid (code name QX-1), PH=11-13.In this solution, also have alkaline degreaser, tensio-active agent and other additives, infiltration by the main solvent molecule, wetting, expansion and solvency action, make superpolymer swelling or dissolving in the carbon distribution, swelling action makes the solid dirt produce internal stress, destroyed the bonding force between carbon distribution and matrix, thereby carbon distribution is removed.Methylene dichloride is the organic solvent of using always, can produce solubilizing reaction with oils, has certain effect to removing heavy oil stain, tar dirt and coke dirt.Sodium lauryl sulphate, 781 is a tensio-active agent, has the minimizing surface tension, wetting infiltration, and unique effect such as emulsification dispersion and solubilising have reduced interfacial tension, have reduced the bonding force between carbon distribution and metallic matrix.And, reduced interfacial tension by the infiltration of tensio-active agent, wetting function, and having reduced the bonding force between pollutent and metallic matrix, the acting in conjunction of these compositions makes carbon obtain removing just.By hyperacoustic cavitation effect and repeated stock effect, destroyed the bonding force of schmutzband simultaneously, made continuous pineization between them at piece surface, and progressively formed the gap, thereby make schmutzband by strip off from level to level,, reach the purpose of removing carbon distribution up to coming off fully.
In mixing solutions of the present invention, sodium hydroxide, tripoly phosphate sodium STPP are inorganic solubility promoter, except that having certain oil removing effect, also have certain penetrating power and dissolving power, especially tripoly phosphate sodium STPP also has certain network and effect, it plays infiltration, dispersion, emulsifying effect by network and effect and schmutzband generation absorption; And EDTA-Na
2Adding can produce complexing action with metal, impel the burning deposits yields dissolving in the carbon distribution,, impel the emulsification and the solubilising of carbon distribution just because of basic solution, tensio-active agent and organic solvent synergy, quickened cleaning, thereby made carbon obtain removing the mixing grease.
In addition, chemical carbon removing method of high-pressure turbine blade of the present invention specifically also has following requirement:
At first use reagent to carry out chemical immersion, the time requirement of immersion is 2～40h, and the further preferred time is 5～20h;
Continue to use reagent to carry out ultrasonic cleaning then, ultrasonic wave action time is 5～50min, and further preferred time range is 10～30min; Ultrasonic wave effect range of frequency is that (preferable range is 25～35KHz) to 20～40KHz;
In chemical immersion and ultrasonic cleaning process, the operating temperature range of reagent is 15～90 ℃, and the operating temperature range of further preferred reagent is 50～70 ℃.
About using above-mentioned special mixing solutions high-pressure turbine blade is carried out concrete selection of process parameters in the carbon remover operating process, we are described as follows:
According to the work characteristics under high-pressure turbine blade inner-cavity structure characteristics and the long term high temperature state, removing the inner chamber carbon distribution not only needs to select effective solution, and cleaning is also extremely important.And only be difficult to remove carbon distribution in the internal organ slit by chemical immersion, we have increased ultrasonic cleaning after chemical immersion is handled for this reason, cavitation effect by ultrasonic cleaning, the huge impact ripple that produces in liquid is stripped from down the carbon of matrix surface, dispersion, emulsification, comes off.Ultrasonic cleaning is suitable for complex structure, the narrow and small part in slit most, is the method that relatively is suitable for to the carbon distribution of removing the blade inner chamber.
(1) test piece adopts homemade sintering test piece, useless blade and people to repair blade respectively in the test.
(2) adopt the test of self-control test piece carbon remover effect comparison:
Respectively with etc. various solution carry out carbon remover and clean, cleaning way adopts chemical immersion and ultrasonic wave physics purging method, and the weight difference before and after cleaning by test piece is weighed the carbon remover effect.Table 2 is respectively the simultaneous test data that adopt special mixing solutions of the present invention (we are referred to as QX-1 in present specification), 781 chemicals of the prior art.
Table 2 QX-1,781 solution comparative test result
Annotate: the employing analytical balance of weighing in the table 2.
(3) test-results of table 2 shows: 1. under the same soaking temperature, same soak time and under same ultrasonic cleaning condition the carbon remover effect of QX-1 solution all be better than 781.2. improving cleaning solution temperature carbon remover effect makes moderate progress.
(4) adopt blade to compare test.These blades repeatedly soak and ultrasonic cleaning by the current technology method, still exceed standard but detect blade inner chamber carbon distribution content through x light, can not normally be delivered for use.Therefore the carbon distribution of these blade inner chambers belongs to the carbon distribution of comparison stubbornness, and to this, we adopt QX-1 solution to carry out chemical immersion and ultrasonic cleaning, have obtained positive effect, and concrete test-results sees Table 3.
Table 3 blade washing test result
Ultrasonic cleaning is a physics cleaning process behind chemical immersion.Ultrasonic wave can make the intravital particle of liquid vibrate near its equilibrium theory of tide when propagating in liquid, thereby produce instantaneous compression and expansion, cause and form temporary transient negative pressuren zone in the liquid, along with hyperacoustic further radiation vibration, the huge impact ripple that produces in liquid is stripped from down the carbon of matrix surface, dispersion, emulsification, comes off.Simultaneously owing to the repeated stock of this effect to the surface, destroyed the bonding force of schmutzband at piece surface, make continuous pineization between them, and progressively formed the gap, this makes the bubble in the liquid can be penetrated into the part internal surface gradually, thereby make schmutzband by strip off from level to level, up to coming off fully.Therefore for having baroque parts such as small gap, deep hole, adopt ultrasonic cleaning very effective.Because the carbon distribution through piece surface after the immersion of certain hour has produced certain dissolving, pine turns usefulness into, the vibration that produces through hyperacoustic cavitation effect again makes the carbon distribution of inner cavity of component obtain removing.The time of ultrasonic cleaning is unsuitable long, to avoid the detrimentally affect of cavitation effect, generally should be controlled in the 10-30min scope.The ultrasonic equipment that we adopt in test is the cleaning equipment of general type, the cavitation effect that ultrasonic wave produces is to be relayed to piece surface indirectly, when this oscillating action is delivered to blade inner chamber slit, obviously weakened, so cleanup action is limited.Especially the intractable carbon distribution to long-term formation adopts common ultrasonic cleaning apparatus to be difficult to remove, and therefore the carbon distribution to special stubbornness should adopt special ultrasonic equipment, and effect can be better.
Improve solution temperature, can further strengthen wetting, infiltration, the solvency action of carbon remover solution, improve cleaning speed.If but adopt higher temperature, the effective constituent in the easy loss solution.The optimal clean temperature should be controlled at 50-70 ℃.
Chemical immersion time and ultrasonic cleaning time will be considered the working time of overhaul machine.Because the carbon distribution of blade surface forms after through long-play, has very strong bonding force with matrix surface, therefore the immersion of short period of time is difficult to remove, and the scavenging solution that adopts us to prepare can not produce detrimentally affect to part, therefore this process using long soak time, purpose makes infiltration, wetting, expansion and solvency action more abundant.Concrete soak time can be controlled in the 5-20h scope, if inner chamber also has carbon distribution, can continue immersion treatment.
To sum up tell, use the carbon distribution that the solution that is used for chemically removing carbon deposition on high-pressure turbine blade of the present invention can be removed the high-pressure turbine blade inner chamber substantially.Detect through physics and chemistry, this solution does not produce any detrimentally affect to Parts Surface Coating.Be used for engine blade production and will obviously improve product percent of pass.
Adopt the cleaning performance of weight-loss method examination for examination QX-1 of the present invention; we have carried out one group of simultaneous test; adopt on-the-spot 781 water-base cleaning liquids (X1) respectively; the special scavenging solution (QX-1) that 781 special-purpose scavenging solutions and the present invention are claimed; by soaking; modes such as ultrasonic cleaning; weightless situation before and after the examination test piece is cleaned; and weigh the carbon remover effect with the weightless situation of test piece before and after cleaning, in soaking solution temperature (25-60) ℃; soak time 6h; every square decimeter of (g/dm of poor quality before and after testpieces cleans under the situation of ultrasonic cleaning time 25min
2), as shown in table 4:
Table 4 QX-1,781 ultrasonic cleaning simultaneous tests
Above-mentioned table 4 test-results shows: under the same soaking temperature, same soak time and under same ultrasonic cleaning condition, adopt the weightlessness value maximum of QX-1 cleaning solution test piece, this carbon remover effect that shows the QX-1 scavenging solution is best.
Adopt the engine blade examination carbon remover effect of the cycle of operation more than 600 hours: in order to examine aqueous cleaning agent that we develop cleaning performance to actual part; we have at first chosen 4 and have tested through the underproof part of current technology cleaning back X-ray check inner chamber from the blade of operation 600h; wherein two are adopted 781 chemicals; other two are adopted the claimed matting solvent of the present invention; and by the X-ray check test effect, the test technology condition is as follows:
The chemical immersion time: 20h; Soaking temperature: 20 ℃-80 ℃; The ultrasonic cleaning time: 20min.We at first detect the blade weight loss before and after cleaning, after again four blades have been carried out X-ray check, the results are shown in Table 5.
Above-mentioned test-results from table 5 is not difficult to find out that the carbon remover effect of QX-1 is fine; qualification rate is very high; significantly better than existing carbon remover technology and 781 chemicals, the present invention's aqueous cleaning agent required for protection being described and using this clean-out system to carry out the chemical operation that removes carbon deposit of high-pressure turbine blade has had tangible improvement to the effect of removing the internal organ carbon distribution.
