Composite liquid for electric arc electrochemical machining of aerospace engine parts

Abstract

The invention discloses composite liquid for electric arc electrochemical machining of aerospace engine parts. The composite liquid is prepared from, by mass, 0.5%-5% of sodium carbonate, 0.1%-1% of disodium hydrogen phosphate, 5%-8% of an anti-rust agent, 2%-5% of an anti-splashing agent, 0.1%-0.5% of a defoaming agent, 5%-10% of a water-based total synthesis agent and 75%-85% of water. The anti-rust agent is a water-soluble antirust agent and mainly comprises phosphoric acid, nitric acid, hydrochloric acid, sodium citrate, sodium sulfite, urotropine, sodium dodecyl benzene sulfonate and zinc sulfate; the anti-splashing agent mainly comprises polyvinyl alcohol and a nonionic surfactant; and the defoaming agent comprises emulsified silicone oil and a polyether defoaming agent. The composite liquid has the beneficial effects that the combination of the sodium salt, the anti-rust agent, the defoaming agent and the anti-splashing agent is adopted, so that the PH stability of the composite liquid is ensured, the arc machining surface smoothness is improved, the loss of an arc cutter is reduced, and the machining cost is saved.
