Increase of productivity of processes of sedimentation of coverings on the restored surfaces of details of cars without decline in quality of the received deposit is a main objective on the way of improvement of galvanic processes. Productivity of galvanic sedimentation depends on the size of potential of the cathode and the anode; from concentration of components of electrolyte about a surface of sedimentation (cathode); from uniformity of delivery and dispersal of ions of metal on a sedimentation surface; from quantity of active sites of the cathode; from nature of passivation of the cathode; from temperature of electrolyte and from the speed of the movement of electrolyte in prikatodny space. Very strongly passivating of a cathodic surface limits the possible growth of productivity of galvanic sedimentation. Passivating consists in education on a surface of the cathode of the continuous passive film consisting of hydrogen, products of reaction of metal with electrolyte components, oxygen of air and foreign inclusions. The passive film is almost insoluble and disturbs electrocrystallization process, shielding a cathodic surface. And cathode covering speed a passive film directly depends on density of cathodic current. It is possible to assume that at achievement of some value of density of cathodic current the speed of formation of a passive film will exceed, the speed of delivery of ions of metal to a cathodic surface and origin of crystals of the besieged metal will become impossible. And on the remained active sites of the cathode where the passive film is absent or has the smallest thickness and growth rate, there will be centers of growth of crystals of metal (dendrites) on which there will be a concentration of the main processes of electrocrystallization. That is the cathodic surface of the restored detail will become covered by the local centers of sedimentation of metal – dendrites. The passive film interferes with growth of limit density of cathodic current at which receiving qualitative electroplated coating is possible. Mechanical elimination of a passive film during sedimentation of a covering considerably facilitates process of electrocrystallization and formation of a layer of metal on the processed detail surface, provides increase of uniformity of the received layer of metal and its microhardness, and also will prevent active formation of local sites of growth of dendrites at the high density of current.

The main purpose of this article is to demonstrate the advantages of statistical analysis of asymmetric relations between test items in the development of computer versions of psychodiagnostic tools. The main idea is that the statistical analysis of asymmetric relations between test items allows to describe the internal structure of the test in the form of incomplete oriented graph. The authors also attempt to identify some areas of possible applications of this analysis in psychodiagnostics and psychometrics: adaptive testing; assessment of discriminatory power of the test task; determining the reliability of the data. The authors base their arguments on analyzing results of 172 subjects tested by the Russian version of MMPI.

Article is devoted to designing of surfaces on the basis of flat 3-fabrics.Such families 3 of lines which block some area of the plane so are called as flat 3 fabric that through each point of this plane passes 3 lines of different families. Functional determinants of this of 3 fabrics anywhere in area doesn't address in zero, two curves of various families have no more than one general point. 3-fabric used in our case is the hexagonal, i.e. consisting of families parallel straight lines. Each line of 3 families bears on itself information on parameters of lines of the modelled surface. On the basis of information which is born on itself by each straight line of three families, some surface is modelled.

In the article presents an analysis of changes in the flow of failures of trucks with diesel and methane-diesel engines. As a result of analysis revealed a change in the reliability of diesel cars converted to work on compressed natural gas. This led to a change in their effective operation because of the increased amount of downtime to repair. Another reason of the decline in effective work vehicles - reduction the carrying capacity, because of the need to transportation a extra weight in the form of compressed gas cylinders. These factors directly affect the final cost of transportation of cargos and payback period of the gas equipment. As a result it was proposed to take into consideration the change in the reliability of methane-diesel vehicles in the formation of cost transportation cargos and payback calculation of gas equipment.

The quasi direct currents, which flows through the winding of power transformer, could cause the migration of working point from the knee of the magnetizing curve to the zone of saturation. In that way, the operational mode of power transformer changes. To account the effect of quasi direct current on the operational mode of power transformer was described the model of winding of power transformer with endless magnetic core and cylindrical magnetic cover. Compare the results of accounting model with the model of winding without effect of cylindrical magnetic cover the 20% difference in the characteristics of inductance from magnetizing current in the area of magnetizing currents under 100A was achieved.
