Ignition Threshold

Nanosecond laser ablation of titanium in air has been studied experimentally. The measured ablation depth at different pulse numbers indicates an incubation effect for the first ∼10 pulses. Compared with steel, the experiments show a larger plasma plume size and lower plume ignition threshold for titanium. The experimental measurements provide very useful information for the further study and practical applications of laser titanium micromachining.

Mechanical Machining

Silicon carbide, due to its unique properties, has many promising applications in optics, electronics and other areas. However, it is difficult to process using mechanical machining or electrical discharge machining due to its electrical insulation, high hardness and brittleness. Laser ablation can potentially provide a good solution for silicon carbide micromachining. However, the study on silicon carbide ablation by nanosecond laser pulses at infrared wavelength is limited, and will be presented in this paper. The laser ablation rate, laser-induced plasma, the ablated surface morphology and chemical composition change have been studied, and the results are discussed.

Titanium has lots of competitive applications in aerospace, biomedical and many other areas due to its special properties. However, the machining of titanium using conventional mechanical approaches often has serious tool wear and low efficiency. Laser ablation can potentially provide a good solution for titanium micromachining. In this paper, nanosecond laser ablation of titanium in air and water has been studied. The laser ablation rate, laser-induced plasma, the ablated surface profile and chemical composition change have been studied, and the results are discussed.
