Description
Известен способ лолучени титанового по крыти из расплава, содержащего низп1ие хлориды титана и хлориды щелочных и. щелочноземельных металлов.There is a known method for obtaining a titanium melt containing a base containing titanium chlorides and alkali chlorides. alkaline earth metals.
Предложенный способ отличаетс от известного тем, что, с целью получени плотных и равномерных осадков сплава титан-ванадий , в расплав ввод т низшие хлориды ванади и анодный сплав титана с ванадием, процесс ведут при температуре 800-900°С и катодной плотности тока 0,1-1,5 а/см. Дл проведени процесса электролитического осаждени сплава примен ют электролизер, выполненный из нержавеющей стали.The proposed method differs from the well-known fact that, in order to obtain dense and uniform precipitation of titanium-vanadium alloy, lower vanadium chlorides and anodic titanium-vanadium alloy are introduced into the melt, the process is carried out at a temperature of 800-900 ° C and cathode current density 0, 1-1.5 a / cm. An electrolytic cell made of stainless steel is used to carry out the process of electrolytic deposition of the alloy.
Исходный расплав состоит из низших хлоРИДОВ титана и ванади . Его готов т путем выдержки солевой смеси низших хлоридов ванади (или титана) и хлоридов щелочных и (или) щелОЧноземельных металлов. Концентраци хлоридов ванади или титана составл ет 2-7 вес. % в пересчете на металл. Этот исходный расплав выдерживают в стальном тигле в течение 8-12 час при 900°С в атмосфере аргона в контакте с измельченным до крупности 5 мм анодным сплавом титана с ванадием. Длительна выдержка обеспечивает установление равновеси между низшими хлоридами титана и ванади с одной стороны и сплавом титан - ванадий сThe initial melt consists of lower chlorides of titanium and vanadium. It is prepared by extracting a salt mixture of vanadium (or titanium) lower chlorides and alkali and / or alkali metal chlorides. The concentration of vanadium or titanium chlorides is 2-7 wt. % in terms of metal. This initial melt is kept in a steel crucible for 8-12 hours at 900 ° C in an argon atmosphere in contact with anodic alloy of titanium and vanadium crushed to a particle size of 5 mm. Long exposure ensures the establishment of an equilibrium between the lower titanium and vanadium chlorides on one side and the titanium-vanadium alloy with
другой. В зависимости от нужного состава покрыти примен ют анодные сплавы с содержанием от 5 до 50 вес. % ванади .other. Depending on the desired composition of the coating, anodic alloys are used with a content of from 5 to 50 weight. % vanadium.
Пример. При осаждении покрыти из электролита, полученного выдержкой исходной смеси хлоридов; хлористого натри , хлористого кали и дихлорида титана (5 вес. % титана) в контакте с анодным сплавом, содержащем 25 вес. % ванади (остальное титан ), за 15 мин получают покрытие, толщиной 100 мк, хорошо сцепленное с катодом. При катодной плотности тока 0,2 а/аи2 в покрытии содержитс 22 вес. % ванади .Example. When a coating is deposited from an electrolyte obtained by holding the initial mixture of chlorides; sodium chloride, potassium chloride and titanium dichloride (5 wt.% titanium) in contact with an anode alloy containing 25 wt. % vanadium (the rest is titanium), in 15 minutes a coating is obtained, 100 microns thick, well adhered to the cathode. At a cathode current density of 0.2 a / a2, the coating contains 22 wt. % vanadium.
Покрыти на стали, полученные но предлагаемому способу, используют в качестве защитных в растворах солей и минеральных кислот.Coating on steel, obtained but the proposed method, is used as a protective solution of salts and mineral acids.
