Получение защитных полимерных покрытий для гидридообразующих сплавов методом механической обработки

TiFe intermetallic compound powder was coated by polymers polytetrafluoroethylene (PTFE) and polymethyl methacrylate (PMMA) using the mechanical treatment in high-energy planetary ball mill. The resulting metal-polymer composites have been studied by electron microscopy, differential scanningcalorimetry, thermogravimetry and X-ray diffractometry. Has been shown the possibility of using mechanical treatment method for the formation protectivecoatings, from the barrier polymers. These polymer coatings are good for protectionof the surface layerson metals and alloysfrom oxidation. Was determined the heat resistance of the obtained polymer coatings. The possibility of the using PMMA and PTFE as a heat-resistant coatings was shown. Such kind of coatings could prevent oxidation of the active metal surface and withstand the heating to the temperatures usually required for the activation of the intermetallic compound TiFe.
