THE DEVELOPMENT OF TECHNOLOGICAL METHODS OF LASER SURFACE TREATMENT OF HEAVILY LOADED PARTS WHEEL SET CARS

Abstract

Possibility of application of processes of laser superficial processing for restoration and increase of a resource of operation of shafts and rims of wheels of railway cars is investigated. The influence of critical parametres of process on depth of a zone of laser influence and their interrelation with the structure obtained and hardness is determineed.
