Direct Laser Deposition with Transversal Oscillating of Laser Radiation

The objective of this research is investigation influence spot diameter, frequency and amplitude of transversal oscillating laser radiation on the efficiency and coefficient of using materials of the direct laser deposition. Efficiency and coefficient of using materials of the direct laser deposition were increased from 15 g/min up to 22.2 g/min and from 27.6% up to 44.4% accordingly at the transversal oscillating laser radiation with spot diameter 0.9 mm, frequency 100 Hz and amplitude 2.6 mm comparatively with seems indicator of the direct laser deposition with spot diameter 3.2 mm without oscillating.
