Effect of acoustic flows on the structure of a constricted glow discharge in argon

Abstract.Research results shows that RF-plasma treatment increases the adhesion of the coating film to the leather uppers and resistance to abrasion and repeated bending of uppers, which define the ability of material to preserve its consumer properties and characterize longer safety of special purpose footwear form during its wearing. IntroductionTextile industry is a significant multiple-discipline sector of the economics, which influences on the stable and balanced social and economic development of the country and provides an independent and intellectual levels of the society. From the branch work effectiveness point and taking into account of situation around the external economic rate huge and massive tasks connected to the renew of high-quality production and continuous process of labor protection improvement need to be solved by the domestic producers [1,2]. High productivity of labour is not only the result of interaction of human, nature and technique but also right organized labor activity.Physical activity and capacity for work of the specialist is provided by the rationally chosen equipment. Enterprises provide their workers with means of individual protection, which include garment and footwear of special purpose. Means of individual protection protect from adverse impact during the operation of work. The main aim of use of means of individual protection is prevention of industrial injuries.Garment and footwear of special purpose are operated in severer industrial conditions than domestic. Because of this the construction and technology of garment and footwear of special purpose have specific features. The level of deterioration of uppers materials are determined by physical activity, which in turn is divided into biomechanical determined by anatomical and physiological features of a man and sanitary and hygienic properties connected to the whole or part hygroscopicity of material [3]. Any means of individual protection, regardless the end use, must be ergonomic, harmless, safe, ensure the unimpeded normal functioning of the human body during the planned period of operation.Materials used at special purpose footwear production differs a lot from the deterioration of model footwear by character and level of exploitation deterioration and also service life. Character, terms of advent and the intensity of defects development of uppers, lining and bottom of footwear are

Abstract. The motion and heat transfer of water droplets with a swirling air flow is investigated. Flow was considered in a cylindrical chamber in the absence of gravity. We created a mathematical model of this problem and made appropriate calculations. The features of the air flow at a tangential feeding it into the chamber, and the motion of the drops, their thermal behaviour are founded. We presented the recommendations for the rational choice of parameters of the apparatus and rational operation regime.

“…The essence of the technology without folding restore worn surfaces of friction units of machines and mechanisms is that RVS additive introduced into regular oil or grease. The preparation is then transported oil on the surface of the friction units, and under the influence of pressure, temperature and and tribes plasma creates conditions for the return of wear on the surface of the wornout place with a partial or full recovery of the geometric dimensions of parts [1][2][3][4][5][6][7]. Thus the formation of layers with high wear resistance and low friction.…”

Abstract. Extending the service life of technical devices by exposing the surface of the friction tribo different drugs is an established fact. There are various hypotheses to explain the mechanism of formation of coatings with high wear resistance and low coefficient of friction on the mating surfaces of friction units of machines and mechanisms during their operation with the presence of drugs Tribo. All these conflicting hypotheses. The proposed technology without the wear operation of equipment using Tribo drugs differ in content and methodology of processing machinery. In this paper, an analysis of existing hypotheses formation mechanism of these coatings. The authors have their own experience in the development and application of technologies without the wear operation of equipment using Tribo drugs. This allows them to develop their own hypothesis of the mechanism of formation of coatings with high wear resistance and low coefficient of friction on the mating surfaces of friction units of machines and mechanisms during their operation with the presence of drugs Tribo.
