Within 30 years, the Belarusian school of scholars has been grown in the field of powder metallurgy; it is more than 20 doctors and 120 candidates of sciences, including 2 academicians and one corresponding member of NAS of Belarus. An advanced school of training for highly qualified scientists has been created.
Fundamental and exploratory research completed during this time, as well as practical development, formed the basis for numerous monographs, articles and tutorials. More than 30 monographs and more than 2,000 articles in total have been published since 1972; 1,225 copyright certificates of the USSR and 53 patents of the Republic of Belarus have been obtained.
A theory of plastic deformation of the porous body has been created, on the basis of which effective methods of cold forging and warm deformation of powder billets have been developed. Technological production processes of parts for various purposes from non-ferrous metal powders and low alloy steels have also been created.
The features and patterns of hot isostatic pressing of alumina, zirconia and their various compositions have been investigated. The processes of sealing single and multicomponent oxide systems at high pressures and temperatures have been described. Research results are used in the production of milling bodies, implants and special machinery products.
The theoretical basis of methods for numerical calculation of multicomponent diffusion processes in heterogeneous sintered steels of Fe-Cr-C, Fe-Ni-C, Fe-Cr-Ni-C composition and alloys of Fe-Cr, Fe-Ni composition. The methods are used in developing technological processes of hardening tool and structural sintered alloy steels.
Theoretical and practical basis have been developed for regulating the structure and properties of porous permeable powder, fiber, mesh and cellular materials, which form the basis for the development and organization in Belarus of industrial production of broad class permeable materials used in various sectors of economy as filters, medical implants, catalysts, silencers, flame arrestors. The results of a group of employees’ research in the Institute in this area have been awarded the Council of Ministers Award of the USSR for 1987.
A theory of electropulse sintering of powders, which was the basis for the creation of industrial technologies for obtaining porous products from powders of refractory and hard-molded materials such as Ti, Ta, W etc., as well as for the development of the process of connecting segments of stone processing tools from CTM on a multicomponent metallic binder with steel backing.
Theoretical and practical bases of technological processes of gas thermal spraying of protective coatings of wide destination (hardening, corrosion and wear resistant, thermal, tribotechnical) onto parts of technological equipment, transport machines and mechanisms, aerospace and special machinery have been developed. A model of particle heating and motion in gas thermal stream allowing to investigate the laws of behavior of the deposited surface and its condition, to regulate and obtain optimal properties of coatings, has been developed. More than 50 specialized sites have been created in Belarus. Developments in this area were awarded the State Award of the Republic of Belarus in 2001.
Theoretical and practical bases of applying thin film coatings in vacuum by chemical and physical evaporation and condensation, which became the basis for the development of technological processes of applying reinforcing, protective and decorative coatings based on TiN onto cutter and dental prostheses, have been developed. The latter development was awarded the State Award of the BSSR in 1986.
A new class of friction powder materials based on iron and powder obtained by processing of steel sludge SS-15, free of lead and asbestos, with low content of non-ferrous metals for use in loaded nodes of tractor and road-building equipment in oil and in conditions of dry friction with improved tribotechnical characteristics, has been developed.
An industrial production technology of billets of continuous current electric machine collectors by cold plastic deformation of sintered copper billet has been developed, which allowed to bring the utilization rate of copper up to 0.96-0.98, to bring the level of product properties up to the level of combined section rolled billet and to increase process performance. The development was awarded the Grand Prix of the European Powder Metallurgy Association in 1997, and the technology was sold to “Zack und Kisselbach GmbH” (Germany) under license.
Biomechanical concepts, design principles, technological processes have been developed, and the production of complete medical implants and their components (dental, maxillofacial, orthopedic, cardiologic, ophthalmologic, oncological etc.) has been organized.
The scientific basis for the creation of functional gradient materials, materials with selective optical properties and nanosized structure, has been developed. The results of research were used to obtain electrotechnical (insulators, magnets, elements of nonlinear optics) and structural ceramic materials.
The scientific foundations have been developed, and industrial production of broad class tool (circular drills, discs, bars, end mills, head, grinding powders and pastes) on the basis of superhard materials (cubic boron nitride, natural and synthetic diamonds) for working stone, building materials, glass and road surfaces, has been created.
Theoretical basis of the method of contact potential difference applied to tribological processes, as well as to the processes of deformation, corrosion and destruction of electroconductive materials, has been developed. The method allows to evaluate defectiveness of semiconductors, metals, powder materials, metal constructions, and loaded elements of transport systems and aircraft.
Theoretical fundamentals of ultrasonic and resistometric nondestructive quality control of powder metallurgy products have been developed. The methods allow to evaluate and investigate the processes of formation of macrodefectiveness during pressing, sintering and plastic deformation of powder materials.
The theoretical bases of intensification of heat and mass transfer in powder capillary structures and improving performance of low-temperature heat pipes have been developed, which is the basis for calculation and optimization techniques of powder capillary structures and heat pipes in general. Mass production of the type series of heat pipes with powder capillary structure and heat sinks of various capacities on their basis for cooling of power commutation systems was organized for the first time in USSR at MolZPM with participation of specialists of the Institute.
A number of new biocompatible and bioactive powder (porous and composite) materials, coatings, technologies of their obtaining and application, designs of dental, orthopedic, cardiologic, ophthalmologic and other surgical implants, have been developed. Their production has been organized.
