The electrical properties of composite nickel matrix electrodeposits prepared under direct current (DC) and pulse current (PC) regimes, are presented in this work. The codeposition of liquid-containing microcapsules (mu caps) along with the metal matrix from electrolytic baths has led to the development of electrocoatings with pre-specified properties. The behaviour of oil-containing polymeric wall mu caps in the nickel matrix for self-lubrication during fretting and cooling during transient contact operation has been investigated. Different preparation conditions have been employed. Their contact resistance and interfacial temperature have been monitored under constant axial contact force using low current excitations. SEM and XRD analysis were applied for the examination of inter-electrode surfaces towards investigating their structural characteristics. (EN)
