The Influence of the Heat Treatment upon the Resistance to Corrosion of the Composite Obtained Using the Electrodepositing of TiO2 in a Nickel Matrix

Abstract

The resistance to corrosion of a composite material obtained using the electrodepositing of TiO₂ in a nickel matrix subjected to heat treatment was studied using the galvanostatic method; the samples were obtained by the electrodepositing of TiO₂ (60%) in a nickel matrix on a copper basis. A Watts electrolyte was used for the electrodepositing. The resistance to corrosion of a sample without composite layer was compared with the resistance to corrosion of a sample with a composite layer subjected to heat treatment.
