The increase in the resource details at their recovery methods of thermal spraying and plasma deposition. Restore the detail methods of thermal spraying and welding is not new to the structures 'Railways'> technology. Leading car-repair business and has long been successfully used consistent with the technology of flame VNIIZhT wire and filamentary sputtering, gas-powder surfacing for the rehabilitation of the resource details. Swarmed by offers, Peter Thiel is currently assessing future choices. All these technologies provide restoration of worn parts of their original properties, allow a few times to return the item in the system. Unfortunately, insufficient investment in R & D 90th – early 2000s led to gaps in technological capabilities VNIIZhT and Russian enterprises that produce and repair equipment for railways.
Modern high-speed robotic systems flame sputtering activated by an electric plating, plasma deposition can reach an order of magnitude higher performance coating, much higher adhesion and cohesion of the coating, significantly more high rates of use of the material. But the biggest advantage of this generation of equipment is a high level of automation of spraying. With the use of robotic systems productivity and quality of repair no longer depend on the skill of the performer, are planned and controlled quantities. All these factors suggest that the use of modern technologies for the repair of equipment allows us to not only recover, but significantly, sometimes several times, increasing the share of the equipment. Each scientific and technical problem can be solved by several ways, and among them can always be found most suitable. Technology flame spraying and fusing good when you want to restore the geometry of the parts which do not undergo severe stress.
The resulting coating have high porosity and relatively low adhesion. It is recognized that plasma surfacing technology best suited for parts that experience shock and alternating thermal loads, such as valves, ICE. Technology high-speed flame spraying is second to none for the rehabilitation and extension of resource components experiencing high corrosion-erosion wear, cavitation due to high density and durability of coatings.
