DEVICE FOR THE LASER-PLASMA SYNTHESIS OF VERY HARD MICROSTRUCTURED AND NANOSTRUCTURED COATINGS

摘要

The invention relates to a device for producing very hard microstructured and/or nanostructured protective coatings on the surfaces of machine and mechanism components. The device comprises a repetitively pulsed laser, a reaction chamber with a means for positioning an object to be treated, having a control processor, and an inlet for a stream of a working gas, a source of a working gas, a means for forming a stream of a working gas in the reaction chamber, a means for delivering laser radiation to the reaction chamber and focusing the beam, and a device for the localized heating of the reaction zone and the simultaneous cooling of the edge of the reaction zone. The reaction chamber has an inlet for a stream of a working gas and an inlet for laser radiation. The invention provides for increased technological potential by enabling the synthesis of coatings which are resistant to wear, impact, chemicals and corrosion, and also provides for a better quality coating by reducing the intensity of residual laser radiation.
