Material removal produced by a high‐power‐density electron beam

摘要

Material removal produced by the interaction of high‐power‐density electron beam with metal was studied theoretically and experimentally. A mechanism of molten metal removal due to the generation of bubbles inside the target metal is proposed, based on the observed phenomenon and the calculation, which takes into account heat‐conduction theory and the penetration of the electron beam into the target metal. Further, as an extension of this mechanism, a drilling mechanism is proposed. These proposed mechanisms could successfully explain the results obtained experimentally.
