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.
In step f), the post-processing includes washing, drying.
Compared with prior art, the beneficial effects of the present invention are:
The present invention provides a kind of electrolyte plasma polishing fluid of aluminium alloy, the present invention is matched by experimental study, optimization
Side, the General Promotion performance of polishing fluid, and provide the polishing process using the polishing fluid.Using the solution of the present invention, throw
Short between light time, effect is obvious, and service life is long；Pernicious gas will not be generated using this polishing fluid, and there are no pollution to the environment.
