INTRODUCTION OF NANOTECHNOLOGIES AT RAILWAY FACILITIES

Abstract

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The paper considers one of the promising directions for obtaining nanopowders by grinding materials in mills of various types and high power, as well as by dispersing alloys with a liquid or gas stream. Such nanopowders can be used as additives in the foundry industry in order to obtain more substantial strength characteristics of products intended for railway equipment. Widespread introduction of nanotechnology will ensure the dynamic development of Russian transport engineering and the creation of economical, highly efficient equipment that meets the requirements of reliability and sustainable operation of the transport complex. The main direction of the introduction of nanotechnologies at railway transport facilities is the use of nanopowders to harden the steels used for production of cars, rails, wheel sets and other strained parts of a railway train. Given the increased need for nanotechnology and nanopowders in the manufacture of modern technology, the question of including in the training programs for specialists in the field of operation of the transport complex sections on the study of the properties and characteristics of nanotechnology and nanopowders is ripe. Keywords: nanomaterials, nanopowders, nanotechnologies, technical means of railways, cars, high-speed railways, railway track, rolling stock.
