Aim\ To prolong the life of fan blade, the surfacing technique is adopted. Methods\ Fan blade is hardened for improving the surface wearing performance of the fan blade. The strengthening methods and the material have been chosen, and the proper process is defined, which have been put into practice. Results\ The life of fan blade has been increased to about four times, and the new process can ensure the fan will not stop working due to wear during the span of life. Conclusion\ The technology of new surfacing is feasible after the proof of the practice. It can be applied in the other application circumstances.
