The discussion centers around the potential for coatings to prevent or slow the sublimation of solids, specifically focusing on steel and its properties in a vacuum. Participants explore the implications of using various coatings and their effectiveness in this context.
Participants generally agree that coatings may have an effect on sublimation, but there is no consensus on the effectiveness or the specific materials that would be suitable as sacrificial coatings. Multiple competing views remain regarding the mechanisms involved.
Limitations include the dependence on the specific properties of the coatings and the conditions under which sublimation occurs, which are not fully resolved in the discussion.
Yes, but it will depend on the coating, the iron may migrate and go into solution in the coating, then evaporate from the coating.Mgt3 said:Could the sublimation of steel over time be prevented or slowed with a coating?

Only the existing surface sublimes, any coating will be sacrificial.
Copper, zinc, a polymer or a paint.Mgt3 said:What could be used as a sacrificial coating for iron or steel?
