Description
At the nodes of the various machines, we use plain bimetal bearings: a steel base - antifriction cladding layer. Bimetal bearings have increased performance. One of the ways of making such bearings is the way of centrifugal bimetallization with heating of the independent electric arc. An important requirement of this technology is a uniform heating of the workpiece along the entire length until the formation of a continuous layer of the molten cladding material. The process of bimetallization require temperature control, since within the movement of the electric arc, low heat or high heat are possible due to heat dissipation from the ends of the workpiece in the installation and from the outer surface of the workpiece to the environment. A viable option the temperature control of the heat process of bimetallization for industrial conditions is to control the temperature of the outer surface of the steel base. It is necessary to solve the heat problem of the relationship between the temperature on the surface of the workpiece with the temperature on the boundary layers. For this purpose the numerical solution of the mathematical model of the thermal process, which includes the heat transmitting equation of Fourier and heat transfer at the ends of the sleeve according to Newton's law. The equivalent coefficients of heat transfer are obtained based on calculated and experimental thermograms. This is a time-consuming work. To minimize the time of fixing the boundary value problem of the thermal process of bimetallization, in this work we present the preliminary modeling based on the analytical solution of the thermal task of bi-metallization

Description
The article deals with issues related to the analysis of the problems of historical and cultural heritage of the Civil War, namely, the role of war in the development of architectural and sculptural symbolism in Krasnodar. It is stated that the historical and cultural heritage, which is kept properly and is presented correctly to younger generation, emerges as a necessary means of regulation and integration of contemporary Russian society. It is noted that the monuments of the Civil War and its participants are a valuable research material for the most complete study of the problem of historical and cultural heritage. It is said that a large number of monuments, that have become an integral part of the appearance of many cities of our country, are constructed after the war in the Soviet Union. Several tens of busts, tombstones and obelisks has been established for died military and civilians during the war. Krasnodar was a survivor of a terrible fratricidal war, where the main element acted Cossacks, was no exception. Memorial monuments and obelisks of human tragedy become an important part of life, both the capital of the Kuban and the entire Krasnodar Territory as a whole. They allow you to save a vivid memory of the tragedy of the Civil War. It is emphasized that Civil War monuments play evident and significant role in the education of the young growing generation now. The conclusion is that the architectural and sculptural symbolism of the Civil War, which is presented in Krasnodar, is multifaceted and diverse. Today it is one of the most important elements of patriotic education and the preservation of the historical memory of a terrible fratricidal war. The architectural and sculptural symbolism, which has prevailed since the end of war and the establishment of Soviet power, carried out and provides a vital link to the past present and future, it contributes to maintaining a sense of patriotism and belonging to the human tragedy of our past

Description
At present, the state management of labor protection in Russia adheres to the goals of harmonizing the domestic legislation with the best world practices in this field, eliminating internal contradictions in legislation and building an active management system for labor protection provided that a «favorable climate» for the conduct of business activities is provided. The regulatory and legal state regulation of labor protection forms the basis for the development and implementation of a set of measures to create conditions for maximum protection of life and health of workers. The authors consider the modern legal framework and standards in the field of management of labor protection in the organization. Reflects the changes that have occurred in the Russian labor legislation regarding the employer's duty to create and maintain a labor protection management system. The aspects of introduction of the health and safety management system are considered taking into account the requirements of the draft international standard ISO/DIS 45001 «Occupational health and safety management systems - Requirements with guidance for use». It is shown that one of the modern directions of standardization in the field of labor protection is the development of risk management and an analysis of foreign practice of legal regulation of issues in the field of occupational safety. The article is intended for specialists in documenting processes carried out implementation, operation and maintenance of a health and safety system, and on students of higher education institutions and teaching staff

THE GREAT PATRIOTIC WAR AND ITS FALSIFICATORS
DescriptionThe authors analyze the results of the lessons and consequences of the Great Patriotic War of 1941-1945 in the context of modernity, as well as falsification attempts to distort, defame and otherwise detract the role of the USSR in the victory over Nazi Germany. They argue that the knowledge of the truth about the Great Patriotic War gives us the opportunity not only proud of the feat of their fathers and grandfathers, our homeland, but also strengthen the belief in the great future of modern Russia. They say that for a long time in Western historiography, and, unfortunately, in the domestic, and plant abstracts, not only contrary to the truth, archival materials and documents, but also the common logic. In particular, the article in question of who is to blame for fueling the war - the Soviet Union and Germany, Stalin or Hitler? The authors argue that, despite some external similarities in politics and ideology of the two historical actors of Stalin and Hitler, the two totalitarian regimes, it is really only superficial similarities. The authors show that it is the ideology and politics of fascism and Nazism became the primary cause of the outbreak of Hitler started World War II, and then the attack on the Soviet Union. The article stated a direct continuity between past and present Nazi fascism, emerging after the coup in the Ukraine with the direct support of the West. The article analyzes and that assistance provided by the Soviet Union and its allies in the anti-Hitler Germany - United States and Britain. Without belittling their contribution to winning, the authors, however, have proved a decisive role of our country in it

Description
Based on the analysis of the phase composition, the average grain size measured by high resolution electron microscopy and multifractal parameterization structure shows the relationship of coating properties with their structural-phase state. The regularities of the evolution of the structural parameters and multifractal characteristics of the surface layers of materials with shape memory can predict the properties of the composition of the "steel-coating". On the basis of experimental studies, it has been shown that mechanical activation of powders of materials with shape memory effect based on TiNiTa makes it possible to create an effective technology training sprayed material which will generate nano-structured surface layers by high-speed flame spraying. The influence of the mechanical activation of TiNiTa powder on the quality of surface layers formed by high-speed flame spraying was investigated, and a significant improvement in the structure of the surface layer was found, with reduced porosity, high adhesion, and, consequently, increased functionality and mechanical properties. The evolution of the structure at all stages of surface modification based on the fractal approach multifractal parameterization method, which is based on qualitative analysis and instrumental methods in addition to classic microstructure parameters like grain size and specific area related to the physical and mechanical properties, is quantitative information. It was established experimentally that after high-speed flame spraying, the performance characteristics of mechanically activated shape memory TiNiTa powder improved: cyclic durability under high-cycle fatigue increased by about 35.6%, and the wear resistance increased by 3.6 times

Description
The article contains a block diagram of the mechanical activation process of multicomponent shape memory materials, taking into account the variety of influencing factors. We have proposed to evaluate the reactivity of the sprayed material using the energy criterion (energy intensity), determined by the additivity concept as an energy amount of the raw material and energy accumulated during mechanical activation. Power consumption of the raw material depends on the chemical and phase composition and is determined based on the similarity between the melting energy, plastic deformation and fracture on the thermodynamic characteristics and diagrams of the systems. The energy stored in the MA is determined on the basis of X-ray structural analysis. We have demonstrated that with increasing of grinding precision there is growth in the number of active centers, which enables nanostructurization of surface layers in high-velocity oxygen-fuel spraying (HVOF). According to the study, we have developed practical recommendations for effective implementation of mechanical activation of the shape memory material
