Abstract

The invention discloses an environment-friendly polishing electrolyte of a titanium alloy and a polishing method, The electrolyte is composed of ethyl alcohol, ethylene glycol, sodium chloride, ammonium fluoride and triethanolamine, the electrolyte comprises the following comments of, 1 to 1-20 of the ethyl alcohol and the ethylene glycol in a volume ratio, 0.01-0.1 mol / L of the sodium chloride inconcentration, 0.01-0.1 mol / L of the ammonium fluoride in concentration, and 0.01-0.05 mol / L of the triethanolamine in concentration. The environment-friendly polishing electrolyte of the titanium alloy and the polishing method provided by the invention have the following characteristics that perchloric acid, phosphoric acid, the sulfuric acid, hydrofluoric acid and other strong acids and the perchloric acid, chromic anhydride, hydrogen peroxide and other strong oxidants which are commonly used in a traditional polishing electrolyte of the titanium alloy are not contained, so that the environmental pollution and the health hazards to operators are effectively reduced; and raw materials are cheap and easy to obtain, the operation cost is low, the phenomena of pitting, bubbles, black and the like are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to an environment-friendly polishing electrolyte for titanium alloys and a polishing method. Background technique [0002] Titanium alloy has the advantages of high toughness, high strength and corrosion resistance, and is widely used in aerospace, shipbuilding, chemical industry, energy and other fields. However, the poor thermal conductivity, high hardness and low elastic modulus of titanium alloy make it difficult to be processed and surface treated. [0003] At present, the polishing methods for titanium alloys can be divided into mechanical polishing, chemical polishing and electrochemical polishing. [0004] Among them, electrochemical polishing is also called electrolytic polishing. Electrochemical polishing is to use the workpiece as an anode, and achieve the effect of surface smoothing and polishing through the selective passivation and dissolution process on the...
