Abstract
The material removal characteristics of TC4 alloy by continuous wave laser irradiation at 1064 nm at an air pressure of 101 Pa is investigated. The morphology of the molten region on the surface of the alloy after irradiation with different laser parameters is studied. The diameter of the molten region and the mass loss rate of the Target are measured in dependence on the laser parameters. With increasing laser power density from 10.5 kW/cm2 to 34.5 kW/cm2 and irradiation duration from 50 ms to 800 ms the morphology of the irradiated spot changes from hollow structure, to a crater and then to a platform, the diameter of the molten region increases from 0.65 mm to 4.16 mm, and the mass loss increases from 0.10 mg to 1.43 mg. With increasing laser irradiation duration, the increasing rate of the diameter of the molten region decreases. The mass loss rate increases with higher laser power densities and irradiation durations. Especially, the morphology of the molten region at low pressure is significantly different from that in atmospheric environment.
