    • The invention relates to a method for coating a workpiece (13) by means of cold gas spraying. Said method is carried out using a cold gas spray nozzle (12) which generates a particle jet (15) that is directed onto the surface (16). Additional energy is introduced into the layer (20) that is being formed by means of an electromagnetic energy source, e.g. a laser (24), while the energy introduced into the particles (19) by the cold gas spray nozzle (12) also contributes to forming the layer. The cold spraying process can be used flexibly as a result of the additional activation by means of electromagnetic radiation (25). Moreover, layers having a complicated structure, e.g. strip conductors, can be created with the aid of the laser (24) without further processing. The invention also relates to a coating unit which comprises a generator (24) for electromagnetic radiation in addition to the cold gas spray nozzle (12) and is therefore suitable for carrying out the disclosed method.
    • 本发明涉及通过冷气喷涂涂覆工件(13)的方法。 所述方法使用产生引导到表面(16)上的颗粒射流(15)的冷气喷嘴(12)进行。 额外的能量被引入到通过电磁能源形成的层(20)中,例如, 激光器(24),而由冷气喷嘴(12)引入颗粒(19)的能量也有助于形成该层。 作为通过电磁辐射的附加激活(25),冷喷涂方法可以灵活地使用。 此外,具有复杂结构的层,例如 可以借助于激光器(24)创建带状导体,而无需进一步处理。 本发明还涉及除了冷气喷嘴(12)之外还包括用于电磁辐射的发生器(24)的涂覆单元,因此适用于实施所公开的方法。
