Изобретение относится к гальванотехнике, в частности к электролитическому осаждению никелевых покрытий, легированных индием до 1%, и может быть использовано в качестве функционального в радиоэлектронной промышленности для обеспечения сварки ультразвуком, а также в качестве коррозионностойкого, защитно-декоративного покрытия в ряде отраслей приборостроения и машиностроения. Электролит для электрохимического осаждения покрытий никель-индий, содержащий сульфат никеля, отличающийся тем, что в состав сульфатного электролита вводят индий в виде хлорида; малоновую кислоту в качестве комплексообразователя, буферной добавки и специфического блескообразователя II рода; и борфторид аммония при рН 2,5 - 3,5.The invention relates to electroplating, in particular to the electrolytic deposition of nickel coatings doped with indium to 1%, and can be used as a functional in the radio-electronic industry to ensure ultrasonic welding, as well as a corrosion-resistant, protective and decorative coating in a number of instrument-making and engineering industries . The electrolyte for electrochemical deposition of nickel-indium coatings containing nickel sulphate, characterized in that indium in the form of chloride is added to the sulphate electrolyte; malonic acid as a complexing agent, a buffer additive and a specific gloss former of the second kind; and ammonium boron fluoride at a pH of 2.5 - 3.5.
