Item type:Наукова стаття, Theoretical and Experimental Studies of the Properties of Porous Permeable Materials Obtained from Industrial Waste(2022-05-25) Povstyanoy, Oleksandr; Imbirovich, Nataliya; Tkachuk, Valentyna; Redko, RostyslavThis article theoretically and experimentally investigates the scientific and technical problem of using multilayer porous permeable materials from industrial waste with controlled functional and technological characteristics by predicting the composition, structure, properties using computer information technology. These porous permeable materials (PPM) from industrial waste are suitable for the purification of technical liquids and gases, which has increased the efficiency of using products in various fields of mechanical engineering. The method of computer modeling proposed by the authors will allow not only to determine the porosity distribution of the filter material but also to determine the relationship between technological and structural parameters. The results of this scientific work are used to develop porous permeable products - filters - for the purification of technical, industrial water, lubricants, and fuels from mechanical impurities contaminants. Developed multilayer porous permeable materials have a higher coefficient of permeability, resource, and dirt capacity with similar single-layer.Item type:Наукова стаття, Numerical Evaluation of the Properties of Highly Efficient Titanium Porous Materials(Cham: Springer Nature Switzerland, 2023-08-21) Povstyanoy, Oleksandr; Imbirovich, Nataliya; Redko, Rostyslav; Redko, Olha; Savaryn, PavloAn exciting combination of such properties as high strength, low den- AQ1 sity, corrosion resistance, and biocompatibility characterizes titanium. However, the widespread use of titanium at the industrial level has not yet been achieved due to its high extraction and production costs. Therefore, titanium is increasingly used in sectors with high demand, such as the aerospace industry or the production of biomedical devices, where the final high cost is not a major factor. It is believed that processing titanium and its alloys using powder metallurgy (PM) methods is a significant way to reduce the cost of manufacturing titanium products. It also provides the opportunity to develop new alloys that are difficult to obtain using traditional technologies. This work is devoted to processing titanium powder from biomedical production waste using various PM methods. It aims to research the processing of almost pure, chemically homogeneous, and finegrained titanium-based components. In particular, the main properties that can be achieved (porosity, microstructure, and mechanical properties) and the creation of highly efficient porous materials by advanced methods of isostatic pressing are presented.
