对风机叶片表面预保护强化技术进行了研究.在被研究的材料中,含WC的镍基喷焊层抗磨性能最好.采用合理的堆焊与喷焊工艺组合,可使风机叶片接近均匀磨损状态,并使风机的使用寿命提高了2～5倍.
The pre-protection and strengthening technology of the fan blade surface was studied.In the studied materials, the WC-based Ni-based sprayed coating has the best anti-wear performance.With the reasonable surfacing and spray welding process combination, the fan blades can be nearly uniform Wear state, and the fan life increased by 2 to 5 times.
