Modeling and Experimental Studies of Thermophysical Properties of Gradient and Combined Materials

Deflection of particles of a laser erosion plume under the action of a high-voltage electrostatic field during ablation processing of titanium

“…An effective method of combined action in the tasks of laser processing of materials is the use of an electric field [6][7][8]. The electric field can facilitate the removal of ablation products from the region of laser beam propagation [9][10][11][12][13][14] or for the formation of an electric arc stabilized by a laser-induced plasma channel (LIPC), which is formed when intense subpicosecond laser pulses pass through the medium in the caustic region of the laser beam [15,16] The use of combined exposure when performing various types of material processing, including the use of laser radiation, is a common practice [17,18]. Usually, laser radiation acts as the main physical impact, additional impacts greatly contribute to an increase in the processing efficiency.…”
