Description
Дл нанесени жаропрочного антифрикционного покрыти индийникель примен ют термический способ - пр мое сплавление компонентов . Кроме того, известно и используетс электролитическое осаждение инди и его сплавов, а также никел и его сплавов из сульфаминовых электролитов.In order to apply a heat-resistant antifriction coating on indikel, a thermal method is used - direct fusion of the components. In addition, electrolytic precipitation of indium and its alloys, as well as nickel and its alloys from sulfamine electrolytes, is known and used.
Недостаток существующих способов заключаетс в значительных потер х инди , неравномерном слое покрыти , а при гор чем способе покрыти в необходимости работы при высокой температуре.The lack of existing methods consists in significant losses of indium, uneven coating layer, and in the case of hot coating method, it is necessary to operate at high temperature.
Описываемый способ осаждени сплавов индий-никель осуществл етс при невысокой температуре и обеспечивает получение равномерного покрыти , хорошо сцепл ющегос с основой и обладающего хорошим блеском, высокой жаропрочностью и коррозионной устойчивостью . Достигаетс это тем, что покрытие нанос т электролитическим способом из электролита оптимального состава при удачно подобранном режиме электролиза.The described method for the deposition of indium-nickel alloys is carried out at a low temperature and provides a uniform coating that adheres well to the substrate and has good gloss, high heat resistance and corrosion resistance. This is achieved by the fact that the coating is electrolytically applied from an electrolyte of optimal composition with a well-chosen electrolysis mode.
Электролиз ведут при температуре электролита 40-70° и катодной плотности тока 2-5 а/дм из электролита, содержащего: 50 г/л сульфаминовой кислоты, 50 г/л сернокислого натри и 0,5-2,0 г/л инди . В качестве нерастворимого анода примен ют графит или платину. В зависимости от содержани инди в электролите на катоде осаждаетс сплав, содержащий 10-40Vo инди . Содержание инди в сплаве пр мо пропорционально его концентрации в электролите, что видно из таблицы.The electrolysis is carried out at an electrolyte temperature of 40-70 ° and a cathode current density of 2-5 a / dm from an electrolyte containing: 50 g / l of sulfamic acid, 50 g / l of sodium sulfate and 0.5-2.0 g / l of indium. Graphite or platinum is used as the insoluble anode. Depending on the indium content in the electrolyte, an alloy containing 10-40Vo indium is deposited on the cathode. The content of indium in the alloy is directly proportional to its concentration in the electrolyte, as can be seen from the table.
