On the Structure of Thin Spectral-Selective Thermal Oxide Coatings on the Surface of X18N10T Steel
The structure of spectral-selective solar radiation absorber coatings fabricated by thermal oxidation of high-chromium X18N10T steel at 400–800° C has been investigated. The structure of the films was controlled by electron microscopy with an X-ray probe and IR spectroscopy. It has been shown that thin thermal oxide layers (400–500 Å) formed during oxidation of steel at 500–600°C had an oxide–oxide composite structure and were characterized by high absorption capacity and a pronounced photoelectric response in the spectral regions of visible solar radiation. The efficiency of the spectral-selective solar radiation absorber coatings prepared by thermal oxidation of high-chromium X18N10T steel at 500–600°C is determined by the thermodynamically conditioned formation of a composite layer of FeCr2O4 granules on the steel surface in the matrix of excess iron oxide and spinel of variable composition in the matrix of the external layer of magnetite.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
