Application of Laser Cladding Nickel based Alloy for Anti corrosion of Chemical Mixing Shaft
Date:2025-12-10 13:32     Source:daokedao     Browse:43

The chemical stirring shaft is stirred in acidic and alkaline solutions, and is susceptible to corrosion and medium erosion. The service life of traditional 316L stainless steel shafts is only 6-12 months. The Daokedao automated laser cladding equipment uses Hastelloy C nickel based alloy powder to melt a 2.5mm anti-corrosion and wear-resistant layer on the surface of the stirring shaft. The cladding layer has excellent resistance to strong acid and alkali corrosion, with a hardness of HRC45-50 and a wear resistance four times higher than stainless steel. The application of a certain chemical enterprise shows that the service life of the mixing shaft is extended to 36 months after melting, and the corrosion rate of the shaft body is ≤ 0.005mm/year. The long axis segmented melting technology of the equipment is suitable for processing mixing shafts over 6 meters.
