Investigation of the possibility of using continuous electron beams for electromotive liner hardening. Final report (Task 3)

PDF Version Also Available for Download.

Description

Continuous laser and electron beams are presently used for surface hardening of steel and cast iron articles. The main advantage of the sources of continuous electron beams over lasers is their high (over 90%) efficiency of conversion of an electric energy to the energy of an electron beam. A promising version of electron-beam system is that including a plasma electron source of the type developed at the Institute of High Current Electronics (IHCE, Tomsk). This type of source has a long lifetime and can operate at a poor vacuum ({approximately} 10{sup {minus}2} torr) in the working chamber. Owing to this ... continued below

Description

Continuous laser and electron beams are presently used for surface hardening of steel and cast iron articles. The main advantage of the sources of continuous electron beams over lasers is their high (over 90%) efficiency of conversion of an electric energy to the energy of an electron beam. A promising version of electron-beam system is that including a plasma electron source of the type developed at the Institute of High Current Electronics (IHCE, Tomsk). This type of source has a long lifetime and can operate at a poor vacuum ({approximately} 10{sup {minus}2} torr) in the working chamber. Owing to this they are successfully used for electron-beam welding, melting-on of hardening coatings, and surface hardening of machine parts. The goal of the present work is to elucidate whether it is possible to use a plasma-cathode continuous electron gun for hardening the internal surface of cast iron liners.
