This work is devoted to improving the technology involved in producing long-length powder permeable materials (PPM) by the dry radial-isostatic pressing (DRIP) method in order to obtain products with a uniform density distribution by volume. Based on the study of density distributions in long-length PPM, we proposed new technological schemes and te...

The article presents the results of theoretical and experimental investigations of the radial-isostatic pressing process of powder materials (PM) in order to improve its effectiveness, to create the new and improve the existing technologies, equipment, tools and PM with the improved properties. For analytical description of the pressing processes w...

Presented scientific work is devoted to increasing the efficiency of abrasive jet machining through the development and implementation of a new, wear-resistant and progressive abrasive jet tool, namely a new designed assembled Venturi type nozzle. A developed design of a nozzle provides the formation of a special air layer on its internal working s...

An experimental complex on a high pressure casing was developed for the research of vibrating processes of powder materials pressing. As a high pressure casing hydraulic hoses of high pressure pressed to the elliptic state were used. Hydraulic pump—a pulsator—is the upgraded gear pump in which a quarter of one tooth was cut. The modes of transition...

Збірне сопло абразивоструменевих машин, яке містить корпус, яке відрізняється тим, щo воно обладнане жорстко закріпленими в корпусі роз’ємними частинами, а саме дифузором, конфузором та розташованою між конфузором і дифузором пористою проникною вставкою

The structure of sandblasting nozzles is subjected to morphological analysis. Metallographic analysis and full processing of microstructural images show that the studied samples can be used in practice. Modern application software is used to develop a technique for determining the structural and morphological parameters of the sample sandblasting n...

The paper presents a new principle of improving the durability of a nozzle for abrasive jet machine. Results of the study on the manufactured porous element (a part of the new design of abrasive jet nozzle) were presented. Conversion of obtained 2D scan results into 3D with the purpose of computer modelling to simulate the air flow through a porous...
