Abstract

Logistics strategy in railway transport provides for a comprehensive solution of four tasks: technical, technological, economic and management. At the same time the technical task is one of the most important, because it ensures reliability of the equipment, an uninterrupted delivery of goods, a reduction of the idle time of locomotives and wagons, which in turn depends on the quality of the repair and the parts used. In the article the main tendencies in field of application of modern metal-ceramic materials for production, repair and operation of railway transport equipment are considered, modern directions in powder technologies and applied materials are shown, as well as possibilities of increasing reliability and safety of used powder parts. The basic properties and advantages of parts from powder materials are estimated. The possibilities of using powder details in various units of rolling stock are shown, as more reliable, safe and economically profitable. Among them: metal-powder slide bearings based on iron-copper, the main advantage of which is the presence of residual porosity, which contributes to the formation of a stable oil film in the bearing; bushings of valves of diesel motors, gears of oil and water pumps possessing high wear resistance; friction discs and brake pads designed to work in brakes and friction clutches in conditions of dry and liquid friction.
