The article reveals the technology of obtaining diffusively alloyed compounds made of metal discard and gives the information concerning the influence of preliminary short term high temperature processing with concentrated energy sources on structure formation within the further induction hard-facing process. A mechanism of a contact eutectic melting in a diffusively alloyed ...

The studies by EPR contactless electrical properties of nanocomposites photoresist in the microwave range of the following results: the maximum ohmic losses are observed for samples at 1.0 × 1017 cm-2, for nickel ions, and iron ions; detected conductivity anisotropy implanted films in the magnetic field.

The article presents the influence of joint and separate reference of fillers (TALC MB, VC PE 175) and stabilizers (RA10) masterbatches on the thermal aging of polyethylene’s composites. It was estimated the thermal stability of polyethylene compositions. The activation energy of thermal oxidative degradation of polyethylene compositions was calculated. Compositions with high ...

The most important task in the manufacture of concrete structures and products to provide the required quality of the front surface of the finished product. Currently, there are quite a number of ways to improve the quality of concrete products and structures surface. One of these ways is isolated unit of the underlying layer in reinforced concrete and concrete structures.

In recent decades, a trend of annually growth in the number of patients with defects of facial skull and cerebral cranium as a result of serious concomitant craniofacial injuries has been emerged. Clinical material is presented by 53 patients in the period of 1985-2008. A technology of fixation of perforated implants of clear titanium by titanium screws was used during reconstructive ...

Two-layer coating of the «thermodiffusion layer – PVD coating TiAlN» was obtained. Microhardness and tribological properties of the resulting two-layer coatings and the contribution of TiAlN coating in integrated micro-hardness of the surface on different substrates was investigated.

Results of comparison tests of the copper coverings created by galvanic sedimentation and the deformation cladding by the flexible tool (DCFT) are given. Delamination tests have shown that the plated coverings do not exfoliate from basis material even at breakdown of experimental samples while electroplated coatings exfoliated on 0,5 cycles of a bend. Tribotechnical tests have ...

There is no doubt that new pre-select gearbox will be the best of automatic transmissions in the near future. That why it is necessary to use innovative methods of diagnostics to avoid unexpectable expenses for repairs. Article gives an information about new method of diagnostics, which is based on computer diagnostics and parallel monitoring of gearbox work in dynamics on special stand.

In the thesis the shortcomings of the modern systems reduce the toxicity of diesel engines. The proposed method improve the performance parameters of a diesel engine using a gas fuel and a system for realization of this effect.

The report describes loosely coupled inertial-satellite navigation system for moving object. The system uses measurements of magnetometric sensor for correction of navigation information. Extended Kalman filter is used for processing the navigation data. The results of modeling the behavior of the system under various driving modes shows an increase in the accuracy of determination ...
