NEW NEED OF STRUCTURAL INTEGRITY TECHNOLOGY FOR COATING-BASED SYSTEMS
Surface Engineering is today becoming an increasingly important discipline to industry where the performance and lifetime of both tools and products are sought to be improved and extended. For instance, coatings are commonly used in several industrial applications. Both soft and hard coatings can inhibit adhesion between the substrate and the counter face resulting in decreased wear, corrosion, etc. Generally, the coating properties are strongly influenced by the deposition method and the selected deposition conditions. The following properties are of great interest for coatings: residual stresses, hardness, and plastic properties, elastic moduli, interfacial adhesion strength. The structural integrity technology has been widely used with great success for the design, manufacture and failure prevention of modern constructions such as chemical and petrochemical plants, power generation and energy conversion systems. However, the researches on the structure integrity, especially the thermomechanical integrity are relatively few.In this paper, the thermomechanical integrity of the coating-based systems with residual stresses was investigated. Different topics were involved, such as residual stress distribution and redistribution in a coating on a substrate, optimal designing methodologies on the basis of residual stress and structural design of crack and delamination resistances for coatings etc.
