| Abstract: | TC4 substrate was remelting by laser remelting.Crystalline phase and microstructure of the coatings were analyzed by X-ray diffraction(XRD),Scan electron microscopy(SEM) and Transmission electron microscopy(TEM).Tribological properties were examined using SRV-IV tester under dry sliding condition.It has been found that the laser remelting treatment can improve the hardness and wear resistance of the as-received TC4,and the crystal size of the as-received TC4 can be refined after laser remelting. |
