摘要:
A filler made of glass beads is provided. The glass improves the absorption and the distribution of the energy of the beam such that an internal wall of the hollow component is not damaged. A process for producing a through-hole in a hollow component is provided. Also, an apparatus for laser drilling is provided.
摘要:
The invention relates to a coating system, especially a low pressure plasma coating system, with at least one treatment chamber and a coating tool, especially a plasma spraying device, wherein at least one pump is provided for evacuation of the treatment chamber, which treatment chamber is formed to be temperature controllable. In addition there is a coating method for low pressure plasma coating with a temperature controlled and evacuated treatment chamber, in which a workpiece is coated by means of at least one coating tool. For acceleration of the coating process, especially the evacuating of the treatment chamber, it is proposed that at least the walls of the treatment chamber and/or the inside of the treatment chamber are temperature controlled at a temperature between 45° C. and 75° C.
摘要:
In internal coating processes there is often the problem that an outer surface of the component to be coated is also coated. The device according to the invention consists in the fact that the outer surface is protected by a robust outer envelope and a filling material between the component to be coated and the outer envelope.
