| 内容： | The invention relates to a method for producing ceramic layers (20) by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream (15), to which particles (19) of the pre-ceramic polymers are added via a conduit (18), is generated by a spray gun (12). The energy for creating a layer (20) on a substrate (13) is produced by injecting a powerful kinetic energy into the cold gas stream (15), thus preventing or significantly restricting the thermal heating of the cold gas stream (15). This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating (20) on a substrate (13) using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness. The invention allows for example armoured layers, thermal protection layers and other functional layers to be produced. |
