Electrodeposition of nickel-based composite coatings from a sulfamate electrolyte

Abstract

Nickel-based composite coatings modified with carbon nanotubes were electrodeposited from a sulfamate electrolyte. The functional properties (friction coefficient, protective power) of these coatings were compared to those of electrodeposited nickel coatings without dispersed phase. Incorporation of carbon nanotubes into nickel coatings leads to a 1.40–1.45-fold decrease in the sliding friction coefficient and to a 1.35–1.40-fold increase in the width of the passive potential range.
