Description
Изобретение относитс к области нолзчени электролитических сплавов, в частности сплавов, используемых в ремонтном производстве . Известен способ электролитического осаждени сплава железо-фосфор в электролите, содержащем хлористое л елезо и гипофосфит натри . Целью изобретени вл етс получение сплава железо-кобальт-фосфор, осадки которого обладают высокой твердостью, в зкостью , износостойкостью, а также хорошо сцеплены с основой; покрыти имеют повышенную стойкость против коррозии. Это достигаетс введением в электролит хлористого кобальта, а также услови ми проведени процесса. Электролитический сплав железо-кобальт-фосфор осаждают в электролите, содержащем (в г/л): хлористое железо450-600 гипофосфит натри 10- 15 хлористый кобальт5- 15 при плотности тока 20-50 а/дм-, рН 0,4-0,8 и температуре 50-60°С. Получаемые осадки имеют мелкозернистую структуру, котора сохран етс при отпуске при температуре 550-600°С. Микротвердость сплава достигает 830 кг/мм и более. Содержание кобальта и фосфора в сплаве колеблетс в пределах: 0,8-3,0% Со и 1,5-4,0% Р. Изменение концентрации гипофосфита натри в пределах 10-15 г/л существеино не сказываетс на качестве покрыти , в св зи с чем корректирование электролита осуществл ют добавлением 4 г/л гипофосфита натри через каждые 40 а час/л. Предмет изобретени Способ электролитического осаждени сплавов железа в электролите, содержащем хлористое железо и гипофосфит натри , отличающийс тем, что, с целью получени сплава железо-кобальт-фосфор, в электролит ввод т хлористый кобальт при следующем соотнощении компонентов (в г/л): хлористое железо450-600 гипофосфит натри 10- 15 хлористый кобальт5- 15 и процесс ведут при плотности тока 20- 0 а/дм, рН 0,4-0,8 и температуре 50-60°С.The invention relates to the field of electrolytic alloys, in particular alloys used in the repair industry. A known method for the electrolytic deposition of an iron-phosphorus alloy in an electrolyte containing chloride is sodium and sodium hypophosphite. The aim of the invention is to obtain an alloy of iron-cobalt-phosphorus, the precipitates of which have high hardness, toughness, wear resistance, and also adhere well to the base; Coatings have improved corrosion resistance. This is achieved by introducing cobalt chloride into the electrolyte, as well as by the conditions of the process. An electrolytic alloy of iron-cobalt-phosphorus is precipitated in an electrolyte containing (in g / l): iron chloride 450-600 sodium hypophosphite 10-15 cobalt chloride 5-15 at a current density of 20-50 a / dm, pH 0.4-0, 8 and a temperature of 50-60 ° C. The resulting precipitates have a fine-grained structure, which is maintained during tempering at a temperature of 550-600 ° C. The microhardness of the alloy reaches 830 kg / mm and more. The content of cobalt and phosphorus in the alloy varies in the range: 0.8–3.0% Co and 1.5–4.0% R. The change in the concentration of sodium hypophosphite within 10–15 g / l does not affect the quality of the coating, Therefore, the electrolyte correction is carried out by adding 4 g / l of sodium hypophosphite every 40 a hour / l. The subject of the invention is a method of electrolytic precipitation of iron alloys in an electrolyte containing ferric chloride and sodium hypophosphite, characterized in that, in order to produce an iron-cobalt-phosphorus alloy, cobalt chloride is introduced into the electrolyte at the following ratio of components (in g / l): chloride iron 450-600 sodium hypophosphite 10-15 cobalt chloride5-15 and the process is carried out at a current density of 20-0 a / dm, pH 0.4-0.8 and a temperature of 50-60 ° C.
