Климат определенной местности нельзя рассматривать изолированно. Особенности климата отдельных регионов это преломление общих закономерностей в конкретной обстановке. Так, погодные условия высокогорных об ластей Кавказа зависят от высотной поясности, циркуляции атмосферы, географического положения, особенностей растительного покрова и других факторов. Результатами данного исследования являются обработка пятилетних дан ных (с 2011 2015 гг.) по температуре воздуха приземного слоя атмосферы и их сравнительный анализ. Данные получены с помощью автоматической метеостанции, расположенной на высоте 1700 м н. у. м. в Безенгийском ущелье. В ходе ис следований было выявлено, что среднегодовая температура приземного слоя атмосферы за 2014 г. была выше таковой в другие годы в 1,5 2,2 раза. The Climate of an area cannot be considered isolated. The climate of certain regions is the refraction of the General laws in a speci c situation. So weather conditions in high mountainous regions of the Caucasus depend on altitudinal zonation circulation of the atmosphere, geographical position, peculiarities of the vegetation cover and other factors. The results of this study are veyears treatment data on the air temperature in the atmospheric surface layer and their comparative analysis. These results obtained at the meteorological station located in Bezengi valley, Kabardino Balkar highmountain reserve.

The article presents theoretical and experimental studies of tribosystems operating under conditions of normal and abnormally low friction and wear when changing the external conditions of their operation. A comparative analysis of self-organization mechanisms of tribosystem operating under conditions of normal mechanochemical and abnormally low friction and wear is performed to determine the conditions of transition to such a mode. There was determined another possible way of converting tribosystems to conditions of abnormally low friction and wear by modifying the surface layer of bronze specimens using finishing treatment with the use of a mineral of amphiboles (jade) group.

The article considers issues of increasing wear resistance of cast iron products by methods of thermochemical treatment of their surface layer. Methods are proposed to solve the problem of wear from cast iron of grade EN-JS1060 due to development of technological processes of strengthening treatment. Alternative versions of strengthening technologies are represented by nitrocarburizing, liquid nitriding and carbonitration. Results of examination of control samples at increasing loads after 200 N before catastrophic wear are given. Comparative analysis of these results showed that samples after carbonitration and liquid nitriding had the greatest bearing capacity (1000 N). Carbonitration is selected as a most preferred option of the surface hardening treatment. Non-poisonous cyanoacid salts are used to realize it.

It has been known for some time that the addition of small oxide particles to an 80 Ni—20 Cr alloy not only increases its elevated-temperature strength, but also markedly improves its resistance to oxidation. The mechanism by which the oxide dispersoid enhances the oxidation resistance is being studied collaboratively by ORNL and INCO Alloy Products Company.Initial experiments were performed using INCONEL alloy MA754, which is nominally: 78 Ni, 20 Cr, 0.05 C, 0.3 Al, 0.5 Ti, 1.0 Fe, and 0.6 Y2O3 (wt %).Small disks (3 mm diam × 0.38 mm thick) were cut from MA754 plate stock and prepared with two different surface conditions. The first was prepared by mechanically polishing one side of a disk through 0.5 μm diamond on a syntron polisher while the second used an additional sulfuric acid-methanol electropolishing treatment to remove the cold-worked surface layer. Disks having both surface treatments were oxidized in a radiantly heated furnace for 30 s at 1000°C. Three different environments were investigated: hydrogen with nominal dew points of 0°C, —25°C, and —55°C. The oxide particles and films were examined in TEM by using extraction replicas (carbon) and by backpolishing to the oxide/metal interface. The particles were analyzed by EDS and SAD.
