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.

ABSTRACTThe breakdown of classical Hall-Petch scaling remains an area of scientific interest, and will govern the limiting strength of nanocrystalline alloys for structural applications. In this work we discuss the hardness and scratch resistance of nanocrystalline nickel and nickel-tungsten solid solution alloys, assessed through nanoindentation and nano-scratch techniques. The materials have been prepared by electrodeposition, and are fully dense with grain sizes between 6 and 22 nm. In this range of grain sizes, there is some evidence for a breakdown of Hall-Petch scaling, reflected in both the hardness and abrasion data. The role of solid solution alloying on this breakdown is also discussed.
