Выход сплава по току составл ет 35% при содержании/ хрома 85-95о/о. Материал анодов - хром или платина. Рекомендуема толщина покрыти 2-3 мк; скорость осаждерш при плотности тока 40 а/дм составл ет 1,0 мк/мин.The current output of the alloy is 35% with a chromium content of 85-95 ° / o. Anode material is chrome or platinum. The recommended coating thickness is 2-3 microns; the sedimentation rate at a current density of 40 a / dm is 1.0 micron / min.
Приготовление электролита. В гор чей дистиллированной воде раствор ют гликоколь и хром треххлористый, в отдельном сосуде - трилон Б и двухлорисгое олово. Готовый олов нный раствор добавл ют к нагретому до кипени хромовому, после чего в электролит ввод т растворенный в теплой воде желатин.Preparation of electrolyte. Glycocol and chromium chloride are dissolved in hot distilled water, in a separate vessel Trilon B and dichloride tin. The prepared tin solution is added to the chromic one heated to boiling, after which gelatin dissolved in warm water is introduced into the electrolyte.
Предлои енный способ впервые позвол ет электролитически получать сплав хром- олово.The proposed method for the first time allows electrolytic production of a chromol-tin alloy.
Осадки сплава хром-олово мелкокристаллические , светло-серые с характерным металлическим блеском. В технологических средах молочной промышленности покрытие сплавом хром-олово обладает лучшими защитнымиThe precipitations of the chromium-tin alloy are small-crystalline, light gray with a characteristic metallic luster. In the technological environments of the dairy industry, chromium-tin alloy coating has the best protective
