Изобретение может быть использовано для нанесения износостойких покрытий на вентильные металлы и их сплавы, получаемые покрытия имеют низкую шероховатость и высокую термостойкость. Сущность изобретения: способ включает в себя оксидирование в импульсном анодно-катодном режиме в щелочном электролите при наложении положительных и отрицательных импульсов сложной формы, длительность положительного и отрицательного импульсов, паузы между ними составляют 100 - 300 мкс. В качестве щелочных электролитов используются растворы фосфатов, боратов, фторидов щелочных металлов в воде, а также для получения термостойких покрытий раствор жидкого стекла и гидроокиси щелочного металла в воде с добавкой мелкодисперсного порошка оксидов, нитридов, карбидов металлов и металлоидов в воде.The invention can be used for applying wear-resistant coatings to valve metals and their alloys, the resulting coatings have a low roughness and high heat resistance. The inventive method includes oxidation in a pulsed anode-cathode mode in an alkaline electrolyte when applying positive and negative pulses of complex shape, the duration of the positive and negative pulses, pauses between them are 100 to 300 μs. As alkaline electrolytes, solutions of phosphates, borates, alkali metal fluorides in water are used, as well as a solution of water glass and alkali metal hydroxide in water with the addition of a fine powder of oxides, nitrides, metal carbides and metalloids in water to obtain heat-resistant coatings.
