Industrial technologies of surface engineering

Surface engineering combines methods for directional changes of physical and chemical properties of the material surface layers by deformation, modification, deposition of films, coatings, protective layers using various combined methods

  • ion thermochemical treatment
  • laser treatment of materials
  • nitrocarburizing
  • induction heating
  • magnetic-pulse treatment and others


New materials

New materials are composite materials such as carbon fiber reinforced plastic, glass-fiber reinforced plastic, basalt fiber reinforced polymers, aramid plastic and metal composites, high-tech ceramics – aluminum, zirconia, oxide, nitride, carbide ceramics and others, new construction materials – new insulating materials from foam glass, modifying agents of roadway surfacing based on rubber powder or polymer fibers, new concrete types. The application range of new materials is the widest – space and aircraft industry, construction engineering, medicine, protection and safety

Metal working

The technology implies changing the shape and dimensions of billets due to the effect of applied forces with a subsequent result saving. The shape and dimensions of the product do not change after the pressure loss. In order to increase the plasticity, metal is heated to the specific temperature before the beginning of the treatment. The temperature is determined individually for each type of the material depending on its specific physical and chemical characteristics

Coatings, deposition technologies and equipment

Depending on the requirements made to operational characteristics of parts, there are three types of coatings

  • protective coatings for protecting the parts from corrosion in various aggressive environments, as well as at high temperatures;
  • protective and decorative coatings for the decoration of parts with simultaneous protection from corrosion
  • special coatings applied to confer special properties for the surface (wear-resistance, hardness, electrically insulating, magnetic properties and others) as well as for the recovery of worn parts


Casting technologies

Casting production is a field of mechanical engineering which deals with formed parts and billets by pouring the molten metal into the moulds where their cavity have the configuration of required parts

In the casting process, metal solidifies in the mould during the cooling process obtaining a casting mold – a finished part or a billet which can be mechanically treated if it is necessary (increase of the dimension accuracy and roughness reduction). In this respect, the casting production has the task to obtain casting moulds where the dimensions and the shape are as close as possible to the dimensions and the shape of the finished part. From 50% to 95% of all parts in machines and industrial equipment are manufactured by casting into moulds


April 25-27, 2022, PTI NAS of Belarus took part in the National exposition of the National Academy of Sciences of Belarus within the International Industrial Exhibition «INNOPROM. Central Asia» (Tashkent, Uzbekistan).

The major directions of the exhibition: mechanical engineering, metallurgy, energetics, chemistry, pharmaceutical industry and medical equipment, industrial automation. The exhibition is focused on expanding industrial cooperation with Central Asian countries, determining new vectors of industry’s development, establishing and enhancing business contacts.

Within the exhibition more than 200 participants from Russia, Uzbekistan, France, Belarus, Kazakhstan, Turkey, Germany (representatives of the largest companies as well as medium-sized enterprises, small business) presented their products.

The Prime Minister of the Republic of Belarus Roman Golovchenko and the Prime Minister of the Republic of Uzbekistan Abdulla Aripov, Ministers and Deputy Ministers attended the exposition of the National Academy of Sciences of Belarus. Apart from that, heads of organizations, scientific institutions and educational establishments of the Republic of Uzbekistan and other countries visited the exposition as well.

PhTI NAS of Belarus presented the developments in the following directions: technology and equipment of ion thermochemical treatment, energy-efficient induction heating technologies and equipment, vacuum-plasma coatings.

Director of PhTI NAS of Belarus Vitali Zaleski visited Tashkent Institute of Textile and Light Industry where the meeting with the Rector of the Institute Ilhom Sabirov was carried out. Both sides discussed the implementation of international projects on creating products of strategic importance imported to the Republic of Uzbekistan.

Director of PhTI NAS of Belarus also visited the Institute of Materials Science of the Academy of Sciences of Uzbekistan to get acquainted with developments and discuss possible ways of cooperation.

As a result of the exhibition, Memoranda were signed with several Institutes of the Academy of Sciences of Uzbekistan. The agreement is reached about signing Agreements of Cooperation and further collaboration in scientific and innovative directions.
