FIELD: technological processes.
SUBSTANCE: invention relates to an apparatus and method for laser deposition of a coating on a sample. Flow of the gas powder mixture and the inert protective gas is fed to the surface of the sample, simultaneously melting the gas powder mixture with a laser beam and moving the sample relative to the laser beam. In the process of surfacing the coating on the sample, the direction of the flow of the powder particles is set by the electric field by transferring the negative particles to the powder particles, and the sample of the positive charge. Device for laser surfacing contains sources of positive and negative charges for controlling the flow of powder particles in an electric field.
EFFECT: technical result of the invention is to improve the quality of the coating formed on the product and to provide the ability to control the direction of travel and the speed of the powder particles.
