Abstract

The invention relates to a coating device and to a method for metal-coating of workpieces, comprising a housing, which surrounds a working space, a retaining apparatus for retaining at least one workpiece in the working space, at least one deposition apparatus comprising a deposition nozzle for applying a metal powder to the workpiece surface to be coated, and a laser for locally melting the metal powder on the workpiece surface to form a coating, and at least one movement apparatus, by means of which the at least one deposition apparatus can be moved relative to the workpiece surface during the coating. Particularly efficient coating is made possible by at least two deposition apparatuses being arranged in the working space in the housing, which apparatuses are designed to simultaneously apply and melt metal powder.
