Description
Technical field
The present invention relates to protective layer on a kind of aluminium workpiece of handling (harteloxierten) at (aluminium) hard anodizing and the method that is used to produce this protective layer.
Background technology
The surface of aluminium matter workpiece is had a stain by the influence of environment usually and is untidy according to its processing (mode).Because aluminium is a kind of softer material, the surface is easy to be damaged out scuffing.
Known, for protection (aluminium) anodic oxidation treatment is carried out on the surface of aluminium workpiece.Anode oxidation method commonly used is electrolysis.Electrolytical selection, electrolytical concentration and temperature, current type and strength of current influence layer formation process.Oxidation grows into depths the material from workpiece surface, wherein can form the maximum layer thickness of 20-25 μ m.
Zone of oxidation is compact grained and has numerous (gas) hole.The hardness of (aluminium) anodic oxide coating is between the hardness of quartzy and silicon carbide.Stone anodic oxide coating is so frangible, to such an extent as to though it can be crooked, can produce minute crack this moment.Therefore, the workpiece for the treatment of anodic oxidation treatment must finally be shaped before anodic oxidation treatment.
Undressed anodic oxide coating is owing to its porousness has very strong adsorptive power, and this causes the erosion resistance of fluid medium to reduce.But described layer can be handled with etch-proof material or isolated material such as wax, glaze lacquer, isolation lacquer etc.It is the painted of anodic oxide coating that the modal technology of adsorptive power is used, and wherein can draw out relatively large particularly organic dye from solution.Painted so colored verity is not very high.Dyestuff just can be dissolved by weak acid.Although inorganic dyestuff is difficult for dissolved, so because little its tinting strength of the degree of depth of infiltration anodic oxide coating is relatively poor.Dyestuff is introduced in electrolytic mode, and therefore this method is very expensive.
In order to prevent to promote the corrosive material to enter, must seal the hole of anodic oxide coating.Anodised, the painted aluminium of possibility seals in aqueous solution, wherein reacts between aluminum oxide and water.By suction volume is increased, thereby the hole is shunk and sealing.
The hardness of anodic oxide coating is owing to this swelling process reduces.The scratch resistance ability of the isolation lacquer that applies is little.The less layer thickness of anodic oxide coating can or scratch mechanical effect owing to cutting and be penetrated, and makes that primary aluminium surface can being etched property nip.This damage can not repaired in the part.
The special case of this protective layer is a hard anodizing horizon, and this hard anodizing horizon can be with obviously bigger layer thickness production and harder, and this layer can not be at random painted.This layer is in strong refrigerative acid bath and produce under higher voltage.It has higher wear resistance and (for example to brinish) stability, therefore as wear protection and corrosion prevention.
Hard anodizing horizon grows from mother metal/base material vertically, therefore can with bigger, up to the layer thickness production of about 250 μ m.This growth increases the volume on component surface, that is size increases.
Compare with common anodic oxide coating, hard anodizing horizon is obviously thicker, and is therefore hard a lot.Because hard anodizing horizon vesicular structure in essence, this zone of oxidation also will carry out aftertreatment to improve or to change the performance that produces.Described hole can be sealed by the density once more in hot water.Make moisture and oxygen be difficult to enter into mother metal by sealing described hole, so just realized the corrosion prevention of obvious improvement.But this protection brings (unfavorable) influence to polishing machine because when density once more by described chromatography go out single gibbsite/Baume stone (
), therefore described layer is weakened in (surface) zone in the above.The also available aqueous PTFE solution in described hole floods.PTFE gives the slip property that hard anodizing (aluminium) has obviously improved.Certainly only can reach the 0 PTFE layer to maximum 3 μ m here, this layer can not bear the wearing and tearing of friction intensive for a long time.In addition, painted only the infiltration in the little layer depth.
For the particular requirement to the surface of aluminium matter microscope underframe/microscope stage, the applicant has researched and developed a kind of with the known ceramic coating of title CeraPlasma.On mother metal, produce conventional anodic oxide coating as increasing attached dose.Spraying a kind of special use/special pottery on anodic oxide coating has added gliding material and (paint) illiteracy and has protected (Versiegelung) in this pottery.The spraying of Rong Hua pottery is at high temperature undertaken by a nozzle, advances from the teeth outwards in this fueling injection grate shape ground.The layer thickness of pottery is the several times of anodic oxide coating.
Ten times of the anodic oxidation floor heights of the hardness of ceramic layer and wear resistance than conventional.Mix the high request that has satisfied erosion resistance by what the pottery and the illiteracy of non-proliferation were protected.The gliding material of introducing is used to optimize the slide/slip of preparations carrier on platform that is formed by sheet glass, prevents that simultaneously preparations carrier is scratched on downside.
Ceramic surface can be made lacklustre and remove (entspiegelt) that reflect, and thereby has prevented undesirable reflection in microscope.This surface does not have dirt and liquid, can clean without a doubt thus.Roughness is minimized, and makes entering of dirt reduce.Stability to solvent and alkali is very high, and therefore general sanitising agent and preparation be erosion surface not.
Processing to pottery needs special knowledge and experience.Preprocessing at high temperature and grid-like coating cause workpiece deformation, and this must eliminate by repairing.Therefore tooling cost is very high.Because the hardness of ceramic layer, this ceramic layer is for particularly the collision in edge is very sensitive.The coating of peeling off can not obtain repairing.Therefore, the flat table top of last usually coating.Described edge, vertical and the downside of platform only have one become the thin anodic oxide coating of black.
Summary of the invention
Therefore, the objective of the invention is to, a kind of protective layer is provided, this protective layer covers the aluminium workpiece that hard anodizing is handled with non-proliferation ground corrosion-resistantly, this protective layer is that non-friable, anti abrasive, anti-cutting and scratch resistance are drawn, and has good slip property, particularly for the Stage microscope of making by glass/target support.The manufacturing of this protective layer should be simply and economical, and should be able to be coated in around the whole work-piece.Damage can both be repaired at any time.
According to the present invention, described purpose realizes like this: described protective layer comprises the compound lacquer of being strengthened by weighting agent.Weighting agent enters in the hole of hard anodizing horizon and fills the roughness on the surface of hard anodizing horizon.Sclerosis by compound lacquer keeps together weighting agent.Because between hard anodizing horizon and compound lacquer, chemical reaction does not take place, kept the proper property of hard anodizing horizon.
Advantageously select the microscope underframe as workpiece.Can monitor the coated materials that forms like this when hard anodizing is handled, promptly introduce a hole in the position that does not have to hinder in workpiece, the actual diameter in this hole can be checked with gauge.The layer of about 50 μ m applies and is proved to be particularly advantageous, because particularly the tolerance of stipulating in the ready-formed threaded hole is just still enough big for final assembling, so that do not need finishing.The painted normally black of workpiece can be complementary with other requirement also.The degree of depth of painted infiltration hard anodizing horizon can be less, but should be dark like this, so that flecked easily canescence hard anodizing horizon seems evenly painted originally.
According to the present invention, compound enamel-cover draw together aromatics, ketone or ester as solvent and Resins, epoxy and resol as the reaction bonded agent.Weighting agent is by preferably by starting material---and the hard powder that silicon carbide, carbide, pottery or diamond are made constitutes.The powder particle size is between 0 to 75 μ m.Advantageously, the hard powder mixture is selected from different starting material and/or different powder particle size.The surface of fracture of powder particle (
) relevant with mother metal consumingly.Therefore, with different granular size (hard powder) together by mixing the envelope density that can in protective layer, produce to the optimization of weighting agent.Hard anodizing horizon has the Vickers' hardness that is about 450-550, and described hard powder has the Vickers' hardness greater than 1200.
Can improve the slip property of protective layer by sneaking into silicone resin and/or PTFE solution.For repair processing or for painted to workpiece better, compound lacquer also can be added with pigment.
Advantageously, after mixing compound lacquer and weighting agent well, at room temperature protective layer is applied.This layer coating can particularly be undertaken by being sprayed in a plurality of steps.For covering the roughness of hard anodizing horizon fully, total bed thickness should be about 20 μ m.
After the dry approximately 30min, about 10min reaches 80-120 ℃ with the workpiece heating, preferably to 100 ℃ in air.Under this temperature, compound lacquer obtains to surpass the flow capacity that applies viscosity.Here, form flow gradient in the protective layer that applies, particularly that granular size is the less hard powder of this flow gradient takes on porous and the coarse hard anodizing horizon to deposit hermetically.Bigger granular size (hard powder) deposition thereon, their gap is filled by smaller particles size (hard powder) equally.At this, compound lacquer is pressed on the surface to a great extent by the segregation (Entmischung) of hard powder.Because the original porousness of (grundgewachsen) that grow on matrix hard anodized surface makes protective layer have very high total adhesion strength.
By further being heated to about 200-250 ℃, preferred 230 ℃, in about 15min, finish baking to protective layer.Here, solvent evaporates and wedding agent is crosslinked.
After baking, also to finish grind protective layer, wherein be the compound lacquer part of grinding basically.The surface obtains lacklustre and unreflected outward appearance thus.Material when correct grinding is removed and is about 5 μ m, and therefore the surface of finishing is almost completely partly formed by the hard powder of density.
Particularly because the layer thickness that the weighting agent in the embedding lacquer applies is less, the anti-cutting of the upper zone of protective layer and scratch resistance are not very high.But confirm surprisingly that in addition little scratch itself can be closed once more automatically.This effect can be roughly similar to automatically mobile (Verlaufen) at glass breakage edge.
Cutting tool and scrape that scribing cutter is local to apply very high pressure with limiting is squeezed in the crosslinked wedding agent filling agent particle by this pressure.More closely near hard anodizing horizon, this effect is just more little for filling agent particle.Confirm, be in hard anodizing horizon under cutting and the scratch remain non-proliferation and to solvent-stable.
Eliminated the bigger damage in the surface in simple mode by replenishing japanning, wherein lacquer also can be added with dye granule.
On the microscope underframe, preferably partly introduce scale or other mark in the edge region.Compare less with enamelled coating with the thickness of hard anodizing horizon owing to painted, so painted and enamelled coating can be with simple mode by engraving, particularly laser sculpture be removed up to hard anodizing horizon, it is marked in the dark protective layer as light color and just displays.Be positioned at mark than the depths with respect to the protective layer surface and do not hinder key property for the wear resistance and the slippage ability of preparations carrier.Because mark is applied on the fringe region on platform surface basically, so the possible disadvantageous effect of tolerable to erosion resistance.
