Electrodeposition and Characterization of Ni-Si Nanocomposite Coatings
Abstract
In this paper is presented morphological aspects and corrosion behaviour of
composite coatings having nickel as metal matrix and silicon as dispersed phase
obtained during electrodeposition process of nickel. Silicon mean diameter size of
particles particles by 50 nm. The Ni-Si composite coatings were electrodeposited
from a suspension silicon particles in aqueous nickel sulphate electrolyte by adding
10g/L and 20g/L of silicon particles in the electrolyte solution. The morphological
aspects of the coatings and inclusion on particles were investigated using SEM and
EDX. As test solution NH4OH 0.5M (specific coke industry) was used in a three
electrode open cell with nickel based nanostructured composite coatings as working
electrode (WE), a platinum electrode as counter electrode (CE) and an Ag/AgCl
electrode as reference electrode (RE).
