Keywords:
laser deposition by powder injection into the molten bath, determination of coat characteristics, influence of injected particles
Abstract
The paper presents a simplified theoretical model for estimating the operating parameters of the laser deposition by injecting the powder into the metal bath. The study considered the influence of the powder particles on the transfer of energy from the laser beam to the surface of the substrate to be deposited. The following parameters were determined: the metal bath depth, the diameter of the metal bath, the mass of the powder deposited, the average temperature of the metal bath, the thickness of the deposited layer.
