Vacuum grows vapor bubbles within the fluid boundary layer on the tube surface.

Vacuum grows vapor bubbles within the fluid boundary layer on the tube surface.

The disruption of the boundary layer generates a faster transfer of etchant to the tube surface.

Pressurizing the chamber slows the etching rate as the boundary layer resists the etchant transfer.
