| Abstract: | This paper studies the effects on pure Fe surface and the microstructure using the method of permeating RE combined with laser melting modification.The results show that after treated,the abrasion of treated sample has been improved significantly and the loss of weight has been reduced to 5%.The microstructure has improved been to be denser and more uniform than that of untreated,grain has been refined and the concentration gradient of the elements permeated has been decreased obviously. |
