The longer the better, and reason is that the chemical property of aluminium is too active, and processing temperature is higher, process time is longer, aluminum alloy surface oxidation
It may be more serious.Therefore, present invention research and disclose electrolyte plasma polishing technological parameter.
Summary of the invention
The object of the present invention is to provide the electrolyte plasma polishing fluid and polishing process of a kind of aluminium alloy, which is used
When aluminum alloy surface processing, polishing time is short and effect is obvious, using simple process, does not generate pernicious gas in use process
And there are no pollution to the environment.
To achieve the above object, present invention provide the technical scheme that
A kind of electrolyte plasma polishing fluid of aluminium alloy includes following component in polishing fluid: sulfuric acid concentration of iron is 2%~
2.5%mol/L, ammonium sulfate concentrations 2%mol/L, additive is several, remaining is water.
The additive include PEG600 concentration be 1%mol/L, citric acid concentration 3%mol/L, EDTA concentration is
0.07%mol/L, gluconic acid na concn are 5%mol/L.
The polishing process of the electrolyte plasma polishing fluid using the aluminium alloy is also disclosed in the present invention, including following
Step:
A) aluminum alloy materials are subjected to polishing pre-treatment；
B) polishing fluid of any of claims 1 or 2 is poured into the polishing trough of electrolyte plasma polishing machine, setting heating
Polishing fluid temperature sets polishing time；
C) aluminum alloy materials are placed on polishing machine hanger, polishing machine hanger connects positive pole, and polishing trough connects power cathode；
D) aluminum alloy materials are completely submerged in polishing fluid by hanger according to certain way dive；
E) polishing time arrives, on-hook rapid increase, and workpiece is made to be detached from polishing fluid；Polishing fluid is the salting liquid of low concentration, can
It is recycled.
F) aluminum alloy materials are subjected to polishing post-processing.
In step a), the pre-treatment includes removing substrate surface dirt.
In step b), setting heating polishing fluid temperature sets polishing time as 1~3 minute to 80~85 DEG C.
In step c), out-put supply is controlled in 300~330V.
