Effect of saccharine on the properties of Ni-Co alloy coatings deposited in citrate electrolytes

This paper presents some results, concerning the effect of organic additive (saccharin) on the composition and morphology of the alloy Ni-Co coatings deposited in citrate electrolyte using two types of deposition - constant potential and pulse potential electrodeposition. It was established, that the presence of saccharin in the electrolyte lowers the Co content in the alloy and makes the coatings shine and smooth with nano-sized crystals with average size in length approximately 200-250 nm and in height under 100 nm.
