Description
Technical field
The utility model relates to the surface spraying aseptic technic field of metallic substance, the particularly device of the cold aluminium-plated alloy of a kind of magnesium alloy hub.
Background technology
China has become World Auto Industry big producing country, and 2011 annual production reach 1,800 ten thousand, for save energy, reduces exhaust gas emission, and automotive industry will develop must realize lightweight.Magnesium alloy is the lighter a kind of structured material of proportion in the known metal material, and is lighter by 3/4 than steel, lighter by 1/3 than aluminium, more application arranged, such as bearing circle, dashboard, seat, wheel casing and engine case etc. in automobile component.On moving parts, wheel hub also begins to use magnesium alloy.Such as the wheel hub on the aircraft and the wheel hub in the racing car, but the application road conditions of these wheel hubs are better usually, and duration of service is shorter.Therefore magnesium alloy hub has general differential arc oxidation, cathode electrophoretic coating, dusts, the surface treatment of baking vanish can meet the demands.But because the alloy ingredient of magnesium alloy hub is more active, after the collision scraping, surface oxidation-resistant ability, easily loss.In order to make magnesium alloy hub can adapt to widely vehicle and to travel on more complicated road surface, stand Stone Shock and collision, scraping, above several surface treatment method all is difficult to meet the demands, because the thickness of magnesium alloy differential arc oxidation is 0.010 to 0.015mm, be unable to undergo complex road surface Stone Shock, scraping, iron staff prizes, collides when also being unable to undergo simultaneously the outsize tire installation.Therefore, adopt the surface treatment of above several magnesium alloy hubs or aseptic technic only to be suitable for wheel and under the splendid condition of road conditions, use, be difficult to adapt to the installation requirements of wheel hub, tire of various oversize vehicles and the requirement of under the relatively poor condition of complicated road and road conditions, travelling and using.
Cold spray technique is a kind of effective ways that generate thick aluminium plated film at Mg alloy surface, and it is by with aluminum alloy granule high-speed impact base material, and the coating that pure viscous deformation polymerization forms occurs particle, can prevent preferably the electrocorrosion of magnesium alloy materials.But formed coating is thinner behind the cold aluminium-plated alloy of the magnesium alloy base material of prior art, the bonding force between coating and the magnesium alloy a little less than.On the other hand, during the cold aluminium-plated alloy of prior art magnesium alloy base material, the sensing of shower nozzle is mostly vertical with spray-coating surface or spraying point, this causes the bonding strength of aluminum alloy granule on the spray-coating surface normal direction direction of spray-coating surface or spraying point (namely perpendicular to) better, and it is relatively poor in the bonding strength that is parallel on spray-coating surface or the spraying point direction, thereby cause the porosity of coating larger, affected work-ing life.Open day is October 17 calendar year 2001, publication number is that the Chinese patent file of CN 2454045Y discloses a kind of supersonic cold-spraying apparatus, the supersonic cold-spraying apparatus that is mainly formed by body, de Laval noz(zle), mixing tank, suction pump line and material feeding box, be carrier by high pressure normal temperature air A, B, injection, mixing and acceleration powder to velocity of sound with on finish material surface modifying.This device utilizes high pressure draft injection coated powder, through de Laval noz(zle) coated powder is accelerated together under the effect of main high-pressure air, makes coated powder clash into the substrate target body under the supersonic speed state, finishes at normal temperatures workpiece surface spraying.Open day is on July 4th, 2012, publication number is that the Chinese patent file of CN102527544A discloses a kind of cold spray apparatus and method for preparing metal composite gradient quasi crystal coating, accurate crystalline flour end powder feeder and the metal or alloy powder powder feeder of this device are connected to the gas-solid mixing chamber by pipeline respectively, form two channels powder feeding structure, be respectively equipped with accurate crystalline flour end well heater and metal or alloy powder heater at described pipeline, gas heater connects the gas-solid mixing chamber by pipeline, in the exit of gas-solid mixing chamber superonic flow nozzzle is set.One of source of the gas pressurized gas enters accurate crystalline flour end powder feeder along separate routes, one enters the metal powder feed device along separate routes, one enters well heater along separate routes, gas and powder enter superonic flow nozzzle by the gas-solid mixing chamber and form gas one solid two-phase flow, solid particulate in the gas one solid two-phase flow is ejected into workpiece surface, serious viscous deformation occurs be deposited on workpiece surface.But said structure all exists between coating and the base material in conjunction with insecure, the problem that coating is thinner and the coating porosity degree is larger.
The utility model content
The purpose of this utility model be for its coating of magnesium alloy hub of solving prior art thin, low with the base material bonding strength, can not adapt to the problem of travelling under the relatively poor condition of complicated road and road conditions and a kind of thick coating is provided, in conjunction with firmly, make the magnesium alloy hub surface possess the device of the cold aluminium-plated alloy of magnesium alloy hub of the Anticorrosive Character of aluminium alloy wheel hub.
Second purpose of the present utility model be for the aluminium alloy covered porosity that solves prior art large, easily be corroded, the problem that work-ing life is short and provide that a kind of coating porosity degree is little, good corrosion resistance, the device of the cold aluminium-plated alloy of magnesium alloy hub of long service life.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: the device of the cold aluminium-plated alloy of a kind of magnesium alloy hub, comprise frame and be arranged on wheel hub driving mechanism on the frame, described wheel hub driving mechanism is provided with the rotating shaft for stationary hub, one side of rotating shaft is provided with the wheel hub heating unit, described wheel hub heating unit comprise one can the holding portion wheel hub heating chamber, the Heating temperature of described wheel hub heating unit is 60 to 230 degrees centigrade, also be provided with on the frame for the shower nozzle to the cold aluminium-plated alloy of wheel hub, shower nozzle be used for its flow of control, the shower nozzle spraying control device of spray speed is connected, the device of the cold aluminium-plated alloy of described magnesium alloy hub also comprises controller, and described controller connects and control wheel hub driving mechanism, wheel hub heating unit and shower nozzle spraying control device.The utility model adopts the cold aluminium-plated powdered alloy of supersonic speed, make the magnesium alloy hub surface possess the Anticorrosive Character of aluminium alloy wheel hub, in the cold aluminium-plated powdered alloy process of magnesium alloy hub outside surface, adopt wheel hub wheelwork and wheel hub appearance thermostatically-controlled equipment, the temperature on magnesium alloy hub surface and the temperature of cold aluminium-plated powdered alloy are matched, make the Al alloy powder on magnesium alloy hub surface accept more even, in conjunction with more firm, plyability is better, thus Effective Raise Al alloy powder thicknesses of layers and uniformity coefficient.Superficial film thickness than the magnesium alloy hub of not heating improves 10-35 doubly, becomes an interior magnesium alloy substrate, the automotive hub of outer aluminium alloy protective layer.Its coating of magnesium alloy hub that has solved prior art is thin, can not adapt to the problem of travelling under the relatively poor condition of complicated road and road conditions.
