Surfacing technology has developed rapidly in recent years and, perhaps because of its specialized nature, its scope and the benefits it provides are not widely recognized. This handbook is intended to improve the understanding by engineers of the wide variety of processes and materials available and to enable them to narrow their choice for given applications. Topics covered include: mechanisms of wear, weld surfacing materials and processes, thermal spraying processes and materials, electrodeposited coatings, physical and chemical vapor deposition techniques, plastics coatings, finishing of surface coatings applied by welding and thermal spraying, quality assurance, safe working, and industrial applications of engineering coatings.
