Application of laser cladding silicon carbide composite powder in the nozzle shaft of sandblasting equipment
Date:2025-12-10 13:41     Source:daokedao     Browse:30

The nozzle shaft of sandblasting equipment adjusts the nozzle angle, which is subject to sand rebound and wear. Traditional stainless steel shafts have a service life of only 1-2 months and are replaced frequently. The Daokedao automated laser cladding equipment uses SiC Co silicon carbide composite powder to melt a 2mm wear-resistant layer at the mating part of the shaft. The hardness of the cladding layer is HRC75-80, and its wear resistance is 10 times higher than that of stainless steel. According to application data from a certain shipbuilding factory, the service life of the nozzle shaft after cladding has been extended to 12 months, and the nozzle adjustment accuracy remains stable. A single sandblasting equipment can save over 8000 yuan in accessory costs annually, and the small component cladding fixtures of the equipment ensure machining accuracy.
