Abstract
Изобретение относится к гальванотехнике, а именно к способу нанесения гальванического покрытия хрома.Способ, согласно изобретению, включает нанесение хромового покрытия из тетрахроматного электролита, который содержит, г/л: CrO3 - 350…400, H2SO4 - 2,5…2,7, NaOH - 40…60, сахар - 1, с использованием источника трехфазного тока и индуктивно-емкостного устройства, соединенного последовательно между отрицательными полюсами источника трехфазного тока и гальванической ванны. При этом, устройство состоит из двух блоков - емкостного и индуктивного, соединенных параллельно между собой, индуктивный блок имеет индуктивность в пределах 0,1 µГн…10,0 Гн, а емкостный блок имеет суммарную емкость в пределах 0,01…0,10 Ф.
