Calculation of process parameters for laser alloying and cladding

This article presents a simplified theoretical model for estimating the operating parameters of laser surface alloying and cladding by the direct injection of powder into the molten bath. It is shown that use of the Mie theory takes into account the influence of the injected particles on laser beam energy transfer to the treated surface. Due to the reasonably good agreement between the calculated and the experimental data, this analytical model is applicable to the development of laser surface alloying and cladding by direct powder injection.
