| Abstract: | For austenitic stainless have an ability of resitance to intergranalar corrosion.Laser surface remelting can effectively eliminate the precipitation phases and remarkably refine the microstructures,which leads to considerable improvement for the corrosion resistance of stainless steel.Disordered state was also observed in a part of the laser surface alloying 1Cr18Ni9Ti surface wiht Nb. |
