摘要: AbstractThe spallation of oxide scales from the steam side tubes in power generation boilers can severely limit component life time. The process involves through scale cracking and crack propagation at or parallel to scale/alloy interface. Many techniques have been developed past two decades assess interfacial fracture toughness brittle coatings on ductile substrates. Analyses mechanics approaches also allow for quantitative determination toughness, which be used time prediction modelling. This paper gives an overview that thermally grown oxides, such as Ni, Fe, Ti, Al, Cr oxides spinels, compare results obtained each type system different techniques. In doing so, limitations technique are illustrated. methods discussed flexure, scratch, indentation, tensile compression tests those perform direct analysis process. data on...
