The mechanism of metal ablation under the effect of an explosion-generated plasma
Abstract
A study is made of the structure of a series of metals and alloys following their exposure to a dense plasma in a shock tube. It is shown that the ablation of the surface layer proceeds in two stages: (1) heating to temperatures well above the boiling point of the metals under normal conditions and (2) explosive volume boiling and melt sputtering due to a pressure drop at the end of a shock.
