Single channel laser cladding layer is prepared on Ti811 titanium alloy surface using synchronous powder feeding laser cladding technology. Microstructure and phase composition of the layer are analyzed with utilization of X-ray diffractometer, scanning electron microscope and energy dispersive spectrometer. The microhardness of the layer is measured with utilization of micro-sclerometer, and friction and wear properties are measured with utilization of the friction wear testing machine and the white-light interferometry profilometer. The results show that the typical Widmanstatten structure is found in the layer. α′-Ti, α″-Ti, and β′-Ti are distributed in the crystal boundary surrounded by α-Ti, and the nano-Ti3Al particles are dispersively distributed in the layer. The highest microhardness of the layer is 480 HV, which is higher than that of the substrate. A large number of nano-Ti3Al particles are dispersively distributed in the layer. Under the action of particles, the friction coefficient decreases and the friction and wear properties increase.
