Tribological behavior of TiN films depositid by reactive magnetron sputtering under low pressure

The effect of deposition conditions on the tribological behavior of titanium nitride thin films produced by reactive magnetron sputtering has been studied. Dependences of the hardness, the width of the friction track, the friction coefficient, and the volume wear of the TiN films on the N₂ reactive gas flow rate have been obtained. Conditions of deposition under which the coatings with the best tribological characteristics are formed have been determined.     

Influence of Titanium Carbides on the Formation of Microstructure and Improvement of the Mechanical Characteristics of Weld Metals

Materials Science - We analyze the possibility of changing mechanical properties of the welds by controlling the amount of acicular ferrite in the structure of the weld metal. We realize the method...     

The use of a fibre based on a polyanhydrouronic acid in medicine

Conclusions It was known previously that salts of the polyanhydrouronic acid obtained from native cellulose are resorbed in the organism during different times.It has been shown that materials based on salts of the polyanhydrouronic acid obtained from viscose silk likewise are not only resorbed but are also completely eliminated from the organism after a definite time.Institute of General and Inorganic Chemistry, Academy of Sciences of the Belorussian SSR; Belorussian Scientific Research Institute for the Textile and Light Industries; Belorussian Scientific Research Institute of Haematology and Blood Transfusion.

Construction of power-generating gas turbine units with the use of efficient thermal schemes

The design features of GTE-30 and GTE-50 power-generating gas turbines, the basic thermal circuit of a PGU-90 (150) combined-cycle plant, and a layout solution for a cogeneration station built around a gas-turbine unit are considered.
