use of a palladium / nickel alloy layer as an intermediate layer between a nichtkorrosionsbeständige or little corrosion resistant metallic surface broken workpiece one by pvd process applied coating

摘要

use of a palladium / nickel alloy layer from the aqueous electrolyte of palladium and nickelamminen with a palladiumgehalt in the range of 2 to 20 g / l, the nickel content in the range of 5 to 30 g / l, and, where appropriate, leitsalzen and organic additives, the sulphur a ufweisen,secluded and the electrolyte, the palladium / nickel ratio is set to a palladiumgehalt alloy electrically isolated from 30 to 90 wt.%, preferably 60 to 85%.-%, which, as an intermediate layer between a nichtkorrosionsbestu00e4ndigen or little corrosion metallic substrate and a pvd process applied after the coating with the understanding that the elektrolytkomponenten so selected that mitabscheidung of sch this is higher than wefel dibasic.
