Abstract

Изобретение относится к покрытию на основе хрома, содержащему хром (Cr), углерод (C) и железо (Fe), причем Cr электролитически осажден из ванны, содержащей трехвалентный Cr. Покрытие отличается тем, что дополнительно содержит никель (Ni), электролитически осажденный из содержащей Cr ванны, включающей по меньшей мере 20 мг∙лкатионов Ni, углерод, по меньшей мере частично, находится в форме по меньшей мере одного карбидного соединения хрома, покрытие было подвергается тепловой обработке при температуре 400-1200°C, или при температуре 400-650°C, или при температуре 650-820°C, или при температуре 820-1200°C, а твердость покрытия, измеренная согласно стандарту SFS-EN ISO 4516, составляет по меньшей мере 1500 HV по шкале микротвердости по Виккерсу. Изобретение также относится к способу получения покрытия и к объекту с покрытием.
