| 摘要 |
The invention concerns a device for coating, using gas diffusion, hollow workpieces, made of heat-resistant alloys of metals such as Ni, Co and Fe, whose outer and inner surfaces are linked to each other by bores. The workpieces are disposed in a container located in a processing chamber (the latter is already known in the art). Workpiece holders are mounted at a low geodesic level with respect to a donor-metal body. The donor-metal body is made of granulated, sintered or solid metal and completely surrounds the outer surface of each workpiece, leaving only a slit. The device is particularly suitable for coating the inner and outer surfaces of power unit blades having cooling-air channels.
