Features of the product formation by the electron beam deposition method

ABSTRACT

Electron beam deposition is a process that involves the use of an electron beam as a source of energy and wire as a raw material for the fabrication of metal products with complex shape in a vacuum and is part of the promising additive technologies group. In this paper a methodology for determining the electron-beam deposition regimes of a wire by the example of corrosion-resistant austenitic steel ANSI 316L is proposed. The proposed calculation methodology connects the main parameters of the process: the electron beam current, the addition wire feed rate, the movement speed of the electron gun and the dimensions of the deposited rollers. The investigation results of the microstructure and properties of the deposited metal are presented. Examples of the obtained cylindrical and conical products are adduced.
