چکیده
Modern branches of chemical production, which are associated with the development light industry, cosmetology, pharmacy, will require introduction new materials and coatings increased corrosionresistance thermal protection properties. Possible ways to solve this important scientific technical problem include finding resource-saving technologies, for authors consider use promising raw create composite coatings. These ash microspheres aluminosilicate composition, waste from power plants operation. The coating is applied by electric arc method on a steel substrate carbon grade A284Gr.D (Cт3) (GOST 380-2005). For their formation, continuously stretched welding wires ferrite-perlite structure brand 1066 (65Г) 14959-79) low-carbon wire ER346 (Св-08) 2246-70) were used. aim work theoretical experimental studies corrosion resistance heat-protective properties coatings.The in naphthalene medium has been experimentally studied: as result immersion 120... 150 days there change color formation an oxide film increase size surface pores 10... 15%. results calculations effective coefficients conductivity linear expansion different filling given. stability thermophysical was confirmed heat sprayed 380-2005), under cyclic loads at temperatures 570 °C/ 10 °C. obtained highlight feasibility using 2246-70), filled composition technologies restoration parts structures equipment. significance thework includes ideas about processes dispersed metal-matrix inorganic maximum resource conditions thermocyclic loads.
