In air plasma-sprayed (APS) coatings, inter-splat pores are roughly aligned parallel to the substrate surface and are accompanied by microcracks and a fine grain size. 84 This pore orientation is highly effective for impeding the flow of heat through the coating. Therefore, APS coatings have low thermal.

The deformation behavior of thermally sprayed partially stabilized zirconia (PSZ) coatings are investigated using Hertzian indentation and four-point bend testing, with in situ acoustic emission monitoring. The experimental deformation curves, together with the corresponding acoustic emission responses and the fracture properties of the material are used in defining the deformation. Traditionally, thermal barrier coatings (TBCs) are used in gas turbine engines to create an insulation layer between the metallic components and the gases in the hot section. Atmospheric plasma spray (APS) is a common method used to produce TBCs.   This chapter discusses the degradation issues for metallic equipment in hydrocarbon fuel conversion processes. Conversion processes cover a wide range of corrosive and fouling environments due to the different sources of fuel (crude oils, natural gas, coal, petcoke, lignin, tar sands, etc.) and a wide range of technologies (hydroconversion, cracking, oxidation, gasification, pyrolysis, etc.).
