Due to brake wear, the tread of railway freight car wheels needs to be repaired every 150000 kilometers of operation. One repair reduces the wheel diameter by 2mm, and the total number of repairs is only 3 times before it needs to be scrapped. Daokedao laser cladding uses bainitic steel material, which is melted in the worn area of the tread. After repair, the tread hardness is HRC38-42, which meets railway standards. The repair cycle has been extended to 450000 kilometers, and the total number of repairs has been increased to 8 times. After being applied by a certain railway bureau in China, the service life of a single wheelset has been extended from 450000 kilometers to 1.2 million kilometers, and the cost of a single wheelset has been reduced from 12000 yuan to 5000 yuan. Calculated based on operating 1000 wheelsets per year, the annual cost savings are 7 million yuan, and the downtime for wheelset replacement has been reduced by 600 hours.
