Gertts O. Conditions of preparation of metastable structures in coatings at base of chromium and their features

Amorphous alloys of chromium-carbon-oxygen system. A phy-sical principles of formation of alloys structure on the basis of chromium during electrodeposition and during the subsequent heat treatment. X-ray diffraction, X-ray spectral, AES, differential ther-mal analysis, scanning electron microscopy, computer simulation. Equipment: ДРОН-3М, ПМТ-3, ЭТА complex "Graphite-2", sca-nning electron microscope "РЭММА-202", "Derxivatoqrapy-Q-150D", AES-spectrometer 09ИОС-10-005. The influence of car-bon and oxygen on chromium structure during electrodeposition have been studied. The relation between physical-chemical and co-rrosion properties of an field of application chromic alloy and its structure is investigated. It is shown that chromium, carbon and oxygen takes part in the formation of an amorphous phase (АP). With the help of theoretical simulation of АP it is shown, that the short-range order of atoms in АP is similar to the order of atoms in crystalline carbide Сr3С2. The range of a thermal stability o f АP is established. Field of application: manufacturing of amorphous ma-terials.
