摘要: Palladium layers are often used as protective on the surface of substrates made copper, nickel and cobalt, well their alloys with each other and/or phosphorous or boron. The known processes, however, allow no adhesive, permanently glossy, bright palladium few pores to be deposited. Such may however deposited from a formaldehyde-free chemical bath which contains salt, one several nitrogenated complexing agents formic acid derivatives at pH value higher than 4. Pretreating in cementation is also possible.
