Abstract
A production process of laser cladding using a coaxial supply layout of powder in the processing zone is investigated. Main attention is paid to investigating the joint influence of parameters of the focused gas—powder jet and focused laser radiation on the properties of the facing layer (sizes, porosity, etc.). The investigation was performed in two directions, notably: 1) numerical modeling (with experimental verification of the results) of focusing the gas—powder mixture by jets of various configurations and 2) modeling by the methods of experimental design. The results of numerical modeling were used when describing the cladding method by methods of experimental design. The data found from the active performance strategy of the investigations showed the statistically valuable influence of these parameters (mutual arrangement of the caustic constriction, shape of the gas—powder jet, treated surface, etc.) on the productivity (sizes) and quality (number of pores) in the facing track.
