Electron-beam physical vapor deposition masking
Hello All, 

Any suggestions on what is the best solution for high temperature (800C to 1000C) Electron-beam physical vapor deposition (EB-PVD) masking for gas turbine aircraft engine? Preferably some sort of tape, so it is easy to use.

Do you want coating metal or ceramic EB PVD coating for gas turbine parts?

For metal - stainless steel
For ceramic - something like Hastalloy X.

Masks element should be on fixture and don’t touch the blade.

There is no tape mask available for EBPVD application. You will need to use metal masking. ERW is the preferred supplier of LPPS and EBPVD tooling for PWA.

The best solution for high-temperature EB-PVD masking will vary depending on the specific needs of your project. Some possible solutions might include using a de-capping or degassing solution, an inhibitor layer for thermal management, or retrofitting with a high-temperature jacket. Higher thermal loads will increase the amount of heat transferred to the atmosphere during deposition, while better process control can help ensure consistent material quality across repeat runs.
