Effect of Saccharin Sodium on the Microstructure and Hardness of Electrodeposited Ni-W Coatings

Article Preview

Abstract:

Nickel-tungsten alloy were fabricated by electrodeposition on carbon steel. The influences of saccharin sodium on the coatings were analyzed using XRD, SEM, and hardness tester. This study reveals that the presence of saccharine sodium has a profound impact on the morphology of the coatings. Moreover, the addition of saccharine sodium tends to enhance the tungsten content in the coatings along with hardness and the grain size of the deposits.
