Exposure of tungsten target to the high-density plasma jet was seen to produce a range of complex micro-structured morphologies (may be polyhedral particles, aggregated hopper or spherulitic structure).
Dear Mr. Sarmah, I am not sure that this is a recrystallization process. During the treatment of a target in high-density plasma jet several physico-chemical processes are being occured. The chemical compositions of solid bodies as well as plasma flows cause the structure of destruction products considerably jointly with general thermal loading conditions.
Thank you Prof. Shabalin. Can you give me some references which can be related to such kind of formation mechanism??
I suggest:

Dear Mr. Sarmah, Thanks for your message with the attachments. However, there is no description of plasma jet conditions. The thing I am mainly interested in is how you could estimate the oxygen concentration there...
