DEVELOPMENT OF NEW TECHNOLOGIES FOR OBTAINING COMPOSITE MATERIALS AND PRODUCTS BY POWDER METALLURGY IN SSI PMI

Yarkovich A.M., Candidate of Technical Sciences, Academic Secretary, Powder Metallurgy Institute of the NAS of Belarus, Minsk, Republic of Belarus

One of the methods for production of composite materials and products is the powder metallurgy, which is the most economical method compared to conventional technologies (casting, machining, pressure treatment). SSI PMI has developed a number of technologies: production of highly porous cellular materials (foam metals) based on nickel, iron, titanium; production of porous frameworks based on carbon felt "Karbopon-active" (Svetlogorsk PA "Khimvolokno"); high-speed flame spraying of multicomponent powder coatings to protect the working surfaces of parts against corrosion and wear; injection molding of spool pairs of distributor ceramic valve.
