Abstract
The invention discloses a method for quickly restoring a partial oxidation film of an aluminum alloy surface. The method is characterized in that firstly, the surface of a part to be restored of an aluminum alloy piece is finished and chemically carried out oil removing; the surface of the part which is not restored of the aluminum alloy piece is shaded; the surface of the aluminum alloy piece to be restored is electrically cleaned to remove the oil; oxidation film restoration is carried out on the surface of the aluminum alloy piece to be restored by an electric brush coating pen; and after being washed with tap water, the restored surface is sprayed with polyurethane paint and is aired. Because the part to be restored of the aluminum alloy piece is used as an anode and the electric brush coating pen is used as a cathode and dips into an electrolytic solution, direct current voltage is applied between the anode and the cathode so as to ensure that the anode on the surface of the aluminum alloy piece, which is to be restored is oxidized so as to form an oxidation film, thereby partially and quickly restoring the oxidation film of the aluminum alloy surface. The piece to be restored does not need to be disassembled and a special oxidation tank is not needed.

(b) with terylene adhesive tape or chlorinated polyvinyl chloride adhesive tape firmly, closely overlay masking is lived the non-reparation part surface of Al-alloy parts, reserves position to be repaired;
(c) to be repaired of aluminium alloy is linked to each other with power cathode, the electric brush plating pen links to each other with positive source, voltage of supply 8～10V, the electric brush plating pen dip in get degreasing fluid on to be repaired surface of aluminium alloy and around move repeatedly, translational speed keeps 10～12m/min, operation 0.5～1.5min, and the degreasing fluid of aluminum alloy surface being detained with tap water is rinsed well repeatedly then, require the surface good, no fluidization tower or extension globule phenomenon to the wettability of water;
(d) to be repaired of aluminium alloy is connect positive source, the electric brush plating pen connects power cathode, voltage of supply 16～20V, dip in brush electric brush plating pen and to get sulfuric acid oxidation solution, move repeatedly on to be repaired surface of aluminium alloy, translational speed keeps 3～6m/min, operation 15～20min; In this process, the electric brush plating pen must maintain competent sulfuric acid oxidation solution;
(e) behind the EO, rinse out the residual sulphur acid oxidase solution on to be repaired surface of aluminium alloy, and dip in the distilled water wipe surfaces, dry in the shade with soft cloth with tap water;
(f) the aluminum alloy surface spraying polyurethane after the oxide film reparation coats with lacquer and dries.
Described degreasing fluid is prepared by first water, and wherein each component content: NaOH is 20～30g/l, Na
2CO
3Be 20～35g/l.
Described sulfuric acid oxidation solution is the first water preparation, H
2SO
4Mass percent concentration is 18～20%.
The invention has the beneficial effects as follows: since with position to be repaired as anode, the electric brush plating pen is as negative electrode and dip in and get electrolytic solution, between cathode and anode, apply volts DS, can make aluminum alloy surface anode electrolysis to be repaired oxidation and form oxidation film layer, repair the aluminum alloy surface oxide film fast thereby reach local, and need not treat repair member and dismantle, do not need special-purpose oxidation trough.
Below in conjunction with embodiment the present invention is elaborated.
Embodiment
Certain many airplane in aeroshow shop, many places, aircraft skin surface occur that coat of painting comes off, lead-covering surface film oxide disrepair phenomenon, this not only influences the specious of aircraft, and if do not carry out repair process timely, corrosion can further expand makes that covering penetrates, aircraft structure connects that causing lost efficacy causes destroying.For this reason, aircraft skin superficial film destruction place needs oxidation again to repair rotproofing.Adopt conventional restorative procedure, to be repaired need be disassembled and send producer in special oxidation trough, to carry out oxide treatment.Owing to aircraft structure aspect reason, actually operating dismantling technology difficulty is on the one hand had relatively high expectations, and has inevitably damage, distortion on the other hand in the process of dismounting, oxidation and installation subsequently again; And this process cycle is longer, needs finish in 8～12 days at least; And must guarantee non-reparation position good insulation operation in the oxidising process, otherwise can cause to be repaired to scrap.
The present invention adopts the electric brush plating pen to carry out partial oxidation film and repairs fast, has realized the reparation to aluminium alloy aircraft skin partial oxidation film, and is time saving and energy saving.
The first step, position to be repaired surfacing and electrochemical deoiling: dip in gasoline or organic solvents such as alcohol or lacquer thinner with cotton yarn, soak into also and clean Al-alloy parts part surface to be repaired repeatedly, remove the remained on surface coat of painting; Successively with 600# and 800
#Abrasive paper for metallograph polishes off Al-alloy parts part surface corrosion layer to be repaired, dips in degreasing cotton then and gets raw spirit scouring removal surface and oil contaminant and dust.
In second step, cover: according to required reparation size, that firmly, closely overlay masking is lived non-reparation is surperficial with terylene adhesive tape or chlorinated polyvinyl chloride adhesive tape, to carry out insulation protection, reserves position to be repaired, causes pollution to prevent that water solution from trickling to non-reparation surface.
