Description
Technical field
The invention belongs to, to the repairing technique field containing titanium composite panel, be specially a kind of repairing using Ultrasonic Arc Sprayed
The method of anticorrosive titanium plate.
Background technology
The density of titanium is small, is only equivalent to the 57% of steel, and titanium has the advantage of steel (intensity is high) and aluminium (quality is light) concurrently simultaneously.It is high
Purity titanium has good plasticity, and in room temperature, titanium is not acted on chlorine, dilute sulfuric acid, watery hydrochloric acid and nitric acid, in actual conditions
Lower titanium is very stable in many media.Titanium is corrosion resistant in the media such as oxidisability, neutral and week reduction because titanium
Affinity with oxygen is very big, in atmosphere or in oxygen-containing medium, one layer of titanium Surface Creation it is fine and close, adhesive force is strong, inertia is big
Oxide-film, protects Titanium base not to be corroded.Therefore going deep into new technological revolution and the industrial revolution, titanium will turn into after
" the 3rd metal " emerged after iron, aluminium.The society that is widely used as of titanium or titanium alloy brings huge economic benefit, is changing
The fields such as work, metallurgy, vacuum salt production, electric power produce huge income.
Using the corrosion resistance of titanium or titanium alloy, one layer of titanium plate, system are combined on other metallic plates with the method for blast weldering
Into composite plate can effectively protect metallic matrix from environmental corrosion.But during weldering of exploding, there is subregion weldering
Close poor, so as to cause foaming between titanium plate and substrate to swell titanium plate, traditional processing method is that titanium plate is all removed into weight
New blast weldering only removes bump and carries out soldering with welding gun in damaged area, such solution complex operation, consumption
When it is longer, realize that efficiency is low.The present invention using Ultrasonic Arc Sprayed to titanium plate breakage repair, to equipment requirement compared with
It is low, the easy to operate easy report and patent realized, yet there are no correlation.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind be well combined with substrate, layer structure into
Divide uniform, free from flaw and the method for repairing and mending containing titanium composite panel being mingled with.
The technical scheme is that：A kind of method for repairing and mending containing titanium composite panel, comprises the following steps：
（1）Titanium plate breakage progress containing titanium composite panel is pre-processed as follows：Decontamination cleaning is carried out to breakage, then using sand

（2）Blasting treatment is carried out to titanium plate breakage：It is 40~60mm that spray gun muzzle, which is adjusted, with workpiece distance, adjusts air pressure regulation
Valve is to 3~6bai（40 ~ 80 pounds/cun 2）, until titanium plate surface is in uniform frosted shape；
（3）Titanium plate is repaired using Supersonic Arc Spraying Technique；Select titanium alloy as hot spraying powder core-wire material, use thermic lance
Carry out Ultrasonic Arc Sprayed and prepare repairing sheet metal；
（4）The repairing sheet metal of preparation is cooled to room temperature, that is, completes repair technology.
Further, described is using titanium alloy sheet as cladding plate, with steel, iron, aluminium alloy, copper alloy or magnesium containing titanium composite panel
Sheet alloy is as substrate, the composite plate being prepared from through explosion welding technique.
Further, the step（3）Titanium alloy hot spraying powder core-wire material, its titanium elements mass fraction be 90%~
99.6%。
Further, the step（3）Ultrasonic Arc Sprayed technological parameter be：Spraying rate is 300~400m/s,
Wire vent speed is 10~15m/s, and spray distance is 110~130cm, 80~90 ° of spray angle.
Further, the step（4）Repair layer consistency it is high, aperture is less than 3 ~ 4nm；Main phase structure is Ti,
A small amount of TiO2；Hardness is 480~680Hv.
The beneficial effects of the invention are as follows：
1. the method for the repairing of the titanium plate containing titanium composite panel of the present invention, the present invention can be damaged to titanium plate using hand-held spraying equipment
Place and buffering area carry out repairing treatment, and spray efficiency is high, and multiple continuous spray can be achieved, and prepared repair layer is uniform, is difficult
Deformation is come off, and thickness can be controlled, with stronger operability, can field patch or on-line operation.
