“…However, their high friction coefficient, weak resistance to wear and bad resistance to high temperature oxidation restrict the application of titanium alloys. Laser melting deposition technology offers an effective way to modify the surface performance of titanium alloys [1][2][3]. Ceramic/alloy and intermetallic composite materials were widely investigated as the laser clad layer for titanium alloys [4][5][6][7][8].…”

To improve the wear resistance of Titanium alloy, TiAl intermetallic claddings were fabricated on TC4 substrate using laser melting deposition technology. Optical microscope, scan electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray diffraction meter were applied to investigate the deposited TiAl layer and their interface with substrate. Using hardness tester and M-2000 wear testing machine, hardness, frictional coefficient and wear resistance of the TiAl layers and TC4 alloy were tested. It was indicated that the deposited TiAl layers were well integrated with TC4 substrate, γ-TiAl and Ti3Al dual phase microstructure was formed in the deposited layer. With higher hardness and lower friction coefficient, the deposited TiAl layer improved the wear resistance obviously comparing to TC4 titanium alloy substrate.

In order to improve the HV hardness and microstructure on the surface of TC4 titanium alloy, the high frequency scan of electron beam (EB) was introduced to treat TC4 titanium alloy. For excellent parameters, the EB energy, focus current and scan times, which will influence the HV hardness and microstructures, were studied. After high frequency scan of electron beam treatment, the HV hardness, modified layer depth and microstructures of TC4 titanium alloy were analyzed. Results show that the HV hardness on the TC4 surface treated by the high frequency scan of electron beam can be increased by almost 40 MPa compared with that of the original material. With improved energy of EB, the depth layer influenced is increased. The focus current adjusted in a narrow range can acquire comparatively better HV hardness on the surface. When the scan times are increased, the HV hardness decreases, and the grains grow up.
