摘要
The influence of process parameters on plasma-assisted boriding of ferrous materials in a BCl3-H-2-Ar atmosphere has been investigated. The elimination of pores in steel substrates is largely influenced by the discharge potential for a fixed BCl3-H-2-Ar mixture. The electrical discharge is characterised by the belt of optical emission spectroscopy. Non-porous boride layers have been applied for oil pump drive gears which were then wear tested. The results show excellent wear protection properties of boride layers produced in a plasma-assisted process. (C) 1999 Elsevier Science S.A. All rights reserved.
