Plasma hardening of ridges of railway wheelsets

Abstract

Plasma surface strengthening plant and processing of the rail rolling stock wheel pairs are described here. Following on from starting the equipment design up to hardened wheel pairs' acceptance, accurate adherence of the process-dependent parameters at plasma treatment, and automated control ensure hardened surface structure and properties stability, as the final result it guarantees road safety.

Keywords:

• plasma hardening
• wear resistance
• wheelset
• monitoring
