Hydraulic column
Product name: hydraulic column
Product material: 27SiMn
Project information: The product is a hydraulic prop on a coal machine. The traditional process is electroplated hard chromium to enhance the surface hardness of the prop to improve wear resistance and corrosion resistance. With the country's emphasis on environmental protection, electroplating companies have reduced costs and other factors. Hydraulic pillar manufacturers have adopted laser cladding technology to replace the traditional electroplating process.

skills requirement:
1. The hardness reaches above 500HV;
2. The thickness of the cladding machine is greater than 0.3mm (single side);
3. The protection level after 200 hours of neutral salt spray (NSS) test is not lower than the level 9 in GB / T 10125-2012;
4. The cladding layer should not have defects such as pores, impurities and cracks.
