Implantation d'azote dans les aciers a outils.

This article originally appeared in the journal 'Heat Treatment of Metals' (UK) 1987, no. 3, p.77-82. In certain cases, ion implantation can constitute a replacement for and in others a complement to, conventional surface treatments or similar processes which aim to increase properties such as wear resistance, fatigue and corrosion resistance and surface hardners. The principles, merits and dements of the process are reviewed and the article focuses specifically on the implantation of nitrogen, which is the most frequently used element for treating plastic moulds.
