Abstract
Incorporation of dispersed particles in an electrodeposit can achieve a diverse range of composite coatings for engineering applications. Anodic or cathodic coatings can be applied via anodising, electroplating and electrophoresis while the included particles can be metallic, polymeric, ceramic, composites or mixtures. This review mainly considers electrodeposited metal matrix coatings. This sub-discipline of electrochemistry and surface finishing can be traced back to Ni-graphite lubricated automotive cylinder engine coatings in the 1920s, followed by developments in the 1960s to 1980s. Recently, particular emphasis has been placed on nanostructured particles to improve deposit properties for applications involving superhydrophilicity, solid state lubrication and in-situ diagnostics. The use of pulsed current, ultrasonic agitation, mixed particles and ionic liquid baths has become more common. The field of composite electrodeposition continues to present many challenges to meet increasing demands for economic coatings, applicable on a workpiece area from mm2 to m2, which are able to withstand arduous in-service conditions. The careful integration of colloid science, electrokinetics and control of operational parameters is critical to achieve a stable suspension of particles in the bath to realise a composite coating having tailored composition, morphology, phase composition, structure and engineering properties. A detailed overview of the reaction environment during electrodeposition, the fundamentals and mechanisms of composite electrodeposition and the influence of process parameters on the final properties of the composite electrodeposits is provided. Important developments in the fabrication of wear- and corrosion-resistant composite films together with applications of composite coatings are outlined.
