| Summary: | Abstract The various technologies of plasma surface hardening of the crests of wheel pairs with regard to the conditions of the Far North are considered by the example of Norilsk enterprises. When considering economic issues the cost of repairing wheelsets were considered. The advantages and disadvantages of each method of plasma surface hardening are shown. Criteria for the economic feasibility of their implementation are established. It is shown that from the standpoint of hardening process cost of one wheel, it is preferable to use the plasma quenching technology in the arc mode. |
