Description
Technical field
The present invention relates to the surface ceramic oxidation technology field of a kind of metal and alloy thereof, the method for particularly microplasma arc oxidation.
Background technology
The surface ceramic oxidation technology of aluminium, magnesium, titanium or its alloy experienced by the development course be oxidized to microplasma arc by anodic oxidation.Microplasma arc surface ceramic oxidation technology is on the basis of common anode oxidation, utilize arc discharge to strengthen and activate the reaction occurred on anode, thus with aluminium, magnesium, titanium or its alloy are the method for the intensified ceramic film of the workpiece surface formation high-quality of material, microplasma arc surface ceramic oxidation technology on workpiece, applies voltage by special mao power source, the metal of workpiece surface and electrolytic solution are interacted, micro-arc discharge is formed at workpiece surface, at high temperature, under the effect of the factors such as electric field, workpiece surface is made to form ceramic membrane, thus reach workpiece surface strengthening and corrosion resistant object.
But no matter domestic or external, microplasma arc oxidation technology does not all enter the large-scale industrial application stage, especially in the production of big area high-level efficiency differential arc oxidation, meet with technical bottleneck.
Its reason is, the state of the art of aluminum current, magnesium, titanium or its alloy surface differential arc oxidization all needs to use high-voltage, and crest voltage generally needs more than 700V, and this has security to restrict for industrial production; Power supply power consumption needed for this technology is large in addition, and the required power of batch production generally will reach hundreds of kilowatt; Current efficiency is also low, and quite a few power consumption on the electrolyte, makes electrolytic solution rapid warm raising, must use electrolytic solution heat sink; In addition, because electric force lines distribution is difficult to control, the controllability of zone of oxidation is also poor.
Summary of the invention
Object of the present invention aims to provide a kind of surface ceramic method for oxidation without the need to high-voltage, high energy consumption, aluminium, magnesium, titanium or its alloy that zone of oxidation controllability is good.
Technical scheme of the present invention is: put in the electrolytic solution by the workpiece being material with aluminium, magnesium, titanium or its alloy, with described workpiece for anode, additional cathode around it, 500V voltage in addition between the anode and cathode, scan at workpiece surface with laser beam simultaneously, thus be oxidized out in-situ authigenic at workpiece surface and become ceramic membrane.
Adopt the inventive method can be oxidized out ceramic membrane at aluminium, magnesium, titanium or its alloy surface in-situ authigenic, thus the workpiece being material with aluminium, magnesium, titanium or its alloy is strengthened, improve its wear resistance and erosion resistance.
The present invention has the following advantages:
1, due to the introducing of laser energy, reduce electrochemical action is transferred to electrical discharge zone threshold value by faraday region, make that the effect of aluminum anode surface electrochemistry is easier is transferred to electrical discharge zone by faraday region, oxidation voltage therefore can be made to be down to below 500V by more than 700V;
2, due to the introducing of laser energy, make direct supply institute consumed power be reduced to below 150KW, the electric current consumed in electrolytic solution temperature rise greatly reduces;
3, due to the controllability of laser beam flying, make the oxidation microplasma arc on anode workpiece surface also obtain controllability, thus make oxide film finer and close, its microhardness reaches as high as 2000HV, and oxidation rate also improves greatly;
4, because voltage of supply reduction, consumed power reduce and oxidation rate raising, this technology is made can to carry out the ceramic alumina of large-area aluminium, magnesium, titanium or its alloy surface.
Present invention process is mainly applicable to the strengthening, wear-resisting and corrosion-resistant of aluminium, magnesium, titanium or its alloy surface.
Electrolytic solution of the present invention to be pH value be 10 ~ 11 alkaline system electrolytic solution, its advantage is: in alkaline electrolyte, and the metal ion that anodic reaction generates is easy to be transformed into electronegative colloidal particle, thus is re-used.
Laser beam of the present invention with the normal angle of workpiece surface be the angle irradiation of 30 ~ 45 ° in workpiece surface, the laser irradiation of this angle makes produced laser coupled plasma body arc stbility best.
The sweep velocity of laser beam of the present invention is 450 ~ 500mm/min, and under this sweep velocity scope, the oxidation ceramic layer compactness produced is optimum.
