| Abstract: | In order to reduce the nozzle cascade erosion by solid particles, Hitachi requires spraying NiCr-Cr32 coating on the outlet side of the 660 MW nozzle cascade. Surface Engineering Research Institute of DTC carries to spray NiCr-Cr3C2 coating by HVAF（Hypersonic Velocity Air-Fuel） on the 660 MW nozzle cascade, it also analyzes the organization and performance of coatings as welt as completed tooling design, programming and other preparatory work for producing. |
