Study of the Formation of the Structure of Laser Tracks During Laser Growing From AlSi10Mg Alloy Powder
The article describes a technique for manufacturing technical samples of AlSi10Mg by laser cladding. The effect of structure and defects on the mechanical strength of this alloy was studied at a process productivity of 1 kg / h and 1.5 kg / h. Mechanical tests for the grown samples are presented. With a decrease in the laser radiation power, a decrease in the dendritic cells of the structure from 204 μm to 46 μm was observed. On a sample with enlarged structure cells and the presence of defects, a significant decrease in the mechanical strength of transverse samples was observed.
