Electrodeposition and Characterization of Ni-Si Nanocomposite Coatings
Journal Title: Analele Universitatii "Dunarea de Jos" din Galati. Fascicula IX, Metalurgie si Stiinta Materialelor - Year 2013, Vol 36, Issue 4
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).

Influence of Normal Loads on Corrosion Behaviour of Ti-6Al-4V Alloy during Fretting in Artificial Saliva
The fretting corrosion behaviour of untreated Ti-6Al-4V alloy in artificial saliva solution was evaluated based on the change in open circuit potential (OCP) measured as a function of time. Fretting corrosion experiments...
A Review on the Thermophysical Properties of Water-Based Nanofluids and their Hybrids
A nanofluid is a solid–liquid mixture which consists of nanoparticles and a base liquid. Nanoparticles are basically metal (Cu, Ni, Al, etc.), oxides (Al2O3, TiO2, CuO, SiO2, Fe2O3, Fe3O4, BaTiO3, etc.) and some other co...
