摘要:
Electrolyte for electrochemical polishing of articles made of titanium and titanium alloys contains 45-70 wt.-% sulphuric acid, 4-20 wt.-% nitric acid, 20-35 wt.-% hydrofluoric acid, 0.4-1.9 wt.-% sodium salt of L-sulphocarboxylic acid containing 17 to 20 atoms of carbon in combination with 0.1-1.6 wt.-% sodium salt of carboxylic acid containing 17 to 20 atoms of carbon or 1-2 wt.-% alkyl sulphoureid, 4-20 wt.-% water.The present invention increases by 20% the dispersive capacity of the electrolyte which produces a high surface finish on the article, uniformity of the electric potential and improves corrosion resistance of the treated article.
