Title:
孔の製造方法
Document Type and Number:
Japanese Patent JP5404128
Kind Code:
B2
Abstract:
The method comprises directing a laser radiation (4) on a surface of a turbine component (1), so that component materials are evaporated and bore (2) is formed. A part volume (2a, 2b) of the bore is formed by departure of a lateral flank (3a, 3b) of the bore with the laser radiation, which is directed so that it includes an angle of greater than 20[deg] and less than 60[deg] with the departed flank. The pulsed laser radiation is directed with a pulse width of 200-500 ns and with a frequency of 28-32 kHz on the surface of the component.
