To expand on moltenmetal's comment, most heat resistant alloys rely on an oxide film that is relatively brittle. Flexing of the convoluted hose will tend to disturb the oxide film, which will result in exposure and re-oxidation of the underlying metal. You might be able to avoid a conflagration...
Hi Jesper,
What CNC mill you are working with? At various times I have used full-sized mills and although I have acquired a Taig CNC mill, I have not set it up due to lack of space. In my experience, intricate machining of annealed OFHC copper is very difficult, which is why I got into...
Hi Jesper,
There are a couple of things to keep in mind for your project. The grain size distribution in the annealed copper will be a function of the annealing process, and the diffusion behavior will be a function of the grain size distribution.
When annealing at high temperatures the...
if one places such a pouch of moisture absorbents inside the vacuum chamber when not in use - if that would be sufficient, or not ... ?
Typical reusable dessicants have a high capacity for moisture, but they do not have a high affinity as evidenced by the rather low regeneration temperatures...
Regarding ceramic insulation inside a vacuum chamber, one should consider that low density ceramic insulation typically has a large surface area that can adsorb moisture. For furnaces that are kept under vacuum when not in use, this is not a problem after initial outgassing. For furnaces that...
