FIELD: working metal by laser beam. ^ SUBSTANCE: method comprises supplying fusing material by means of a jet of transporting gas to the nozzle of laser installation coaxially to the laser beam. The laser installation is adjusted to focus the laser beam inside the nozzle at a distance of 3-7 mm from the nozzle exit. The focus of the flow of the powder fusing material is outside of the nozzle at a distance of 6-10 mm. The particles of the zirconium dioxide are embedded into the melt of the heat-resistant high alloy and are distributed homogeneously through the bulk of the plated metal. ^ EFFECT: enhanced resistance to heat. ^ 1 ex |
