Pulse electrodeposition and characterization of nano Ni-W alloy deposits

► The alloy was found to have higher microhardness than nickel and an increase in the wt% of W in the alloy deposits. ► On the alloy surface, long needle type grains were seen. The grain size was in the range of 50-80 nm. ► The EDAX analysis revealed the % of W in the alloy as 30.99%. ► The increase of W addition offered the alloy deposits enhanced corrosion resistance.
