Performance evaluation of railway wheels repaired through laser directed energy deposition (DED-LB)

The International Journal of Advanced Manufacturing Technology
Abstract Railway wheels and rails wear is probably one of the biggest challenges in the maintenance of transportation system. In modern high-speed trains, maintenance costs can represent almost a third of the total life costs, where the wheelset wear is one of the most common and costly phenomena.
