This article presents general design principles for different types of surface-finishing processes, such as cleaning, organic coatings, and inorganic coatings applied by a variety of techniques. It discusses the factors that influence the selection of surface-finishing processes. These include fabrication processes, size, weight, functional requirements, and design features. The article discusses the design as an integral part of manufacturing. It contains tables that summarize the design limitations for selected surface-preparation, organic finishing, and inorganic finishing processes.
