Dehydration behavior gives a hint about thermal properties of materials. It is important for the usage areas and transportation of minerals. Magnesium borates can be used as additive materials in areas such as in the production of superconducting materials, in the composition of detergents, due to the content of boron in the friction-reducing additives in oils and insulating coating composition...

The problem of calculating the required adhesion strength and accuracy measuring adhesive/cohesive thermally sprayed coatings (thermal barrier, electrically insulating, irradiation) on a cylindrical test specimen is practical interest from point view improving reliability highly loaded parts internal combustion engines agricultural machines, various aerospace nuclear industries. There have been...

Liquefied natural gas (LNG) is one of the most promising fuels for energy supply because it has a favorable combination environmental and economic properties in connection with new trends aimed at development ecological sustainable consumption resources, which ensure constant growth LNG consumption. The article presents an analytical review main technical solutions construction cryogenic pipeli...

The violent event of a short-circuit leads to short-term exposure of circuit breaker components to extremely high current, causing thermal degradation, vaporization and deformation of some components and the deposition of surface contaminants. After short-circuit, the leakage current carried by the breaker, when voltage is applied, increases dramatically but must remain below a certain threshol...

A conductive metallic particle in a gas-insulated metal-enclosed system can charge through conduction or induction and move between electrodes on insulating surfaces, which may lead to breakdown flashover. The the charging time vary depending spatial electric field intensity, shape, electrode surface coating. charged under influence of field, it discharge become electrically when colliding with...

Abstract Coatings prepared from chromia-rich (Al,Cr) 2 O 3 solid solution (ss) feedstock powders are intended to improve the properties of Cr coatings, but rarely studied so far. In this work, processability a commercial powder containing 78 wt.% by atmospheric plasma spraying (APS), corresponding coating microstructures and were investigated. Possible further improvements expected blending wit...

Abstract In the fields of military industry, national defence and major engineering, oriented silicon steel is an indispensable material, but chromium-containing insulating coating coated on its surface harmful to environment humans. Due poor performance, industrialization chromium-free inorganic hindered. To improve corrosion resistance for steel, reduced graphene oxide (rGO) was prepared by h...

During the production of deep oil and gas, scaling, waxing, hydrate ice plugging other problems easily occur. To solve these problems, reducing temperature loss pipelines is a feasible method. In order to protect outer wall coating from being damaged losing its thermal insulation performance, this paper proposes developed technology for novel inner coating-insulated pipeline. A new temperature-...
