Изобретение относитс к электрохимическому полированию титана и его сплавов и может бьпь использовано в машиностроении , самолетостроении, электротехнике и приборостроении,The invention relates to electrochemical polishing of titanium and its alloys, and can be used in mechanical engineering, aircraft manufacturing, electrical engineering and instrument making,
Цель изобретени - повышение отражательной способности поверхности и снижение ее шероховатости.The purpose of the invention is to increase the reflectivity of the surface and reduce its roughness.
Повышение качества полировани достигают электрохимической обработкой металла в электролите на основе серной и плавиковой кислот с добавками этиленгликол и моноэтаноламина.Improving the quality of polishing is achieved by electrochemical treatment of the metal in the electrolyte based on sulfuric and hydrofluoric acids with the addition of ethylene glycol and monoethanolamine.
Полирование ведут на аноде при температуре раствора 40-65°С. анодной плотности тока 100-140 А/дм2, напр жении 8-13 В в течение 2-3 мин. В качестве катода ис- польэуют титановый электрод с площадью, в четыре-восемь раз превышающей площадь анода. После полировани изделиеPolishing is carried out on the anode at a solution temperature of 40-65 ° C. anode current density of 100-140 A / dm2, voltage 8-13 V for 2-3 minutes. A titanium electrode with an area four to eight times the area of the anode is used as the cathode. After polishing
промывают сначала холодной, а затем теплой водой.washed first with cold and then with warm water.
Концентраци компонентов электролита вл етс оптимальной. При выходе концентраций кислот за предлагаемые пределы качество полировани резко снижаетс в результате травлени поверхности или формировани на ней нерастворимой окисной пленки.The concentration of electrolyte components is optimal. When the concentration of acids exceeds the suggested limits, the quality of polishing decreases sharply as a result of etching the surface or forming an insoluble oxide film on it.
Органические добавки - этиленгликоль и моноэтаноламин - создают в зкий слой в прианодном слое электролита и уменьшают растравливание поверхности. Выход концентраций органических добавок за предлагаемые пределы приводит к растравливанию поверхности и снижению качества полировани .Organic additives — ethylene glycol and monoethanolamine — create a viscous layer in the near-anode electrolyte layer and reduce surface etching. The yield of concentrations of organic additives beyond the proposed limits leads to surface etching and a decrease in the quality of polishing.
В таблице представлены данные по составу и свойствам предлагаемого раствора .The table presents data on the composition and properties of the proposed solution.
