On contact of an aqueous solution containing poly-N-vinylpyrrolidone and copper sulfate with a steel surface, copper(II)ions are reduced on the steel surface to give nanocomposites comprising copper nanoparticles and the polymer. Ultrasonication of the reaction system results in the nanocomposite sol. Copper oxide nanoparticles formed upon decomposition of the nanocomposite and oxidation of copper nanoparticles at high temperature are active catalysts of steel nitriding. © 2015 Pleiades Publishing, Ltd.

Technologies for accounting of motorways' characteristics with an implementation of automated video monitoring systems allow to automate operations of complex evaluation of motorways and provide means for objective uniform evaluation of motorways' infrastructure condition. The paper presents recommendations for application of video monitoring for purposes of establishing of monitoring and recording and client-server model of motorways. The proposed approach for video monitoring is aimed for improving currently operated accounting systems for data on condition of infrastructure. Key components of video monitoring system for engineering data of transport and operational characteristics of a motorway are studied and practically applied in production by specialists of "Geotrans" laboratory of MADI. © Copyright EM International.

The interference stress relaxation in a composite repair bandage formed on a cylindrical metal surface was studied. The creep of a repair ring bandage under the action of interference stresses was evaluated. The results of the calculation of the creep and the interference stress relaxation of a composite ring on a sample made of a segment of a metal pipe in time are presented. © 2016, Pleiades Publishing, Ltd.

The differential effect of technological heredity on the characteristics of adhesives and operating properties of adhesive joints has been considered on the basis of the main technological operations of the bonding process. Based on an expert assessment of the main characteristics of the adhesive material (with the exception of fracture shear stress and ultimate tensile strain), it has been found that technological operations of the bonding process have no effect on technological heredity. This conclusion is controversial; to take into account this effect, we suggest using the synergistic effect. © 2016, Pleiades Publishing, Ltd.

The relationship of each stage of the process with the mechanics of destruction during operation of parts has been shown by the example of problems of modeling of engineering solutions during the fabrication of parts prepared from polymer materials. When using partially cross-linked thermoplastic filled polymers containing a slight amount of typical components, it has been shown that modeling of process solutions is an iterative process, in which structural defects, which differ by scale levels, are formed during each individual technological operation. © 2016, Pleiades Publishing, Ltd.

In Moscow Automobile and Road Construction University, investigations are carried out in the field of Diesel engine working process perfection for complying with prospective ecological standards such as Euro-6 and Tier-4. The article describes the results of the first stage of experimental research of the influence of injection pressure up to 3000 bar on working processes of Diesel engine and its fuel system. Justification of the design of a common rail injector for fuel injection under 3000 bar pressure is presented. The influence of raising injection pressure (up to 3000 bar) on the fuel spray propagation dynamics is demonstrated. The combined influence of injection pressure (up to 3000 bar) and air boost pressure on fuel spray propagation dynamics is shown, including on engine emission and noise.

The problems of surface hardening of high-carbon steels by alloying using laser radiation are considered. The effect of the laser treatment parameters on the thickness, the structure, the phase composition, the microhardness, and the residual stresses of the surface layer is studied, and the influence of alloying elements on the strength of the surface layer in carbon steels and their wear resistance is investigated. © 2015, Pleiades Publishing, Ltd.

Different factors of technological heredity for parts prepared from metals and polymer composite materials are comparatively analyzed. The factors most affecting the inheritable information are considered, the influence of the transfer method is studied, and regions where inheritable information appears are listed. Technological links providing transfer of the inheritable information from one technological operation to another are considered. © 2015, Pleiades Publishing, Ltd.
