Is the errosion in the sealed gas area or the electrical connection area? or somewhere else?
If it is eroding around you HV connections its probably electrolysis from disimilar metals coupled with the HV.
You would have to change the connector to the same material as the annode so as not to get material migration.
Thats all I got as a guess.
and where do you get your honeycomb material for you laser bed and how much does it cost?
thanks
