| Abstract: | The laser overlaying was adopted on the revoling working blades according to invalidation of the decanter centrifuge abrasion, the technique of obtaining the performance of well metallurgy bond and microstructure minute was researched. It shows that the hardness of laser overlaying advance 2 times, the resistance to abrasion advances 5 times. It has practical value on decanter centrifuge blade. |
