P2-12: Increase of Wearproofness Steel Surface as a Result Mechanochemical Influence Polymethylmethacrylat: Volodymyr Tsyganov1; 1"Zaporizhzhia Polytechnic" National University
The analysis of efficiency influence products destruction high molecular connections is presented in composition a lubricating - cooling liquid on the change of mechanical properties metals in the zone of contact tribocouplings and at treatment of metals cutting. Perspective of application here of additives рolymethylmethacrylat is shown for the increase of wearproofness details of the tribomechanical systems, providing of efficiency lathe treatment. Complicated mechanochemical character of interaction рolymethylmethacrylat is considered with a metal depending on the terms of dynamic loading of contacting surfaces.Keywords: wearproof surface, superficial layer, nanostructural state, tribocoupling, destruction polymer

P2-13: Increased Efficiency Serfising Diffusion Metalization of Cast Iron and Steel Chemical Equipment Parts: Svetlana Kondrashova1; Egor Saprykin1; Valeriy Naumyk2; Sergey Sheyko3; 1Berdyansk Mechanical Engineering College of National University "Zaporizhzhia Polytechnic"; 2NU "Zaporizhzhya Polytechnic"; 3Zaporizhzhia National University
The level of gray cast iron and steel parts performance characteristics subjected to diffusion metallization is determined by the set of the saturated layer parameters: depth, phase composition and distribution, porosity, structure of the sublayer and layer. Based on the mathematical models obtained the "diffusion property – mixture composition" diagram are constructed, which allow to determine the optimal composition of the saturating mixture. It is established that during diffusion titanium plating the optimal amount of cadmium chlo-ride in the saturating mixture is 6…10%. It is established that the diffusion titanium saturating mix-ture, containing 8…10% aluminium, provides the high-quality surface coating having a continuous carbide layer.In diffusion chromium plating the presence of ferromanganese in the saturating mixture in-creases the diffusion layer relative wear resistance coefficient for steel by 10…15 times, for cast iron by 20…25 times relative to the diffusion layer obtained in the mixture that does not contain ferromanganese.

P2-14: Production Aluminized Alloyed Coatings for Protection Against Wear and Corrosion: Borys Sereda1; Dmytro Sereda1; Irina Kruglyak1; 1Dneprovsky State Technical University
For machines and units operating in corrosive environments, an important characteristic is corrosion resistance. To increase the corrosion resistance it is necessary to saturate the surface layer with elements that will form passive skin. In our case, when the ionic passivation potential is reached, oxide films are formed, with the following composition - Cr2O3, Al2O3, TiO2, SiO2, which protect the metal from destruction. Coatings were tested in 30% acid solutions HCl and H2SO4.When tested in a 30% solution of hydrochloric acid (HCl), the best resistance was shown by chromium-aluminum-silicified and chromium-alumina-titanated coatings having correspondingly weight loss values of 18,8 and 16,7 g/m2. Comparative analysis of corrosion resistance of protective coatings obtained in isothermal conditions showed that they have a weight loss of 1.7-2,1 times more.
