Optimization of the shape of nozzles for coaxial laser cladding

摘要

The results of mathematical modelling of the flows of powder in nozzles for coaxial laser cladding are presented. The modelling results are used to determine the optimum geometrical parameters of the nozzle used for the construction of appropriate technological equipment. Calculations are carried out to determine the optimum values of the flow rate of powder, the size of powder particles, the geometry of the powder flow and the distance from the outlet of the nozzle to the surface of the components. The resultant values were used in the development of technological processes of cladding with powders of different composition.
