WebVery high fluence implantation of 14N+ ions was used to promote the formation of a nitride layer on the surface of steel coinage dies used by the Portuguese Mint. Die steel samples were studied before and after implantation at 90 keV plus 30 keV for two nominal fluences, 5.0 × 1017 at/cm2 and 1.0 × 1018 at/cm2, and for two implantation temperatures, room … WebIon implantation was performed on single-crystal CVD diamonds produced by ElementSix. The samples have 100 crystal orientation, size 3×3×0.5 mm3 and are classified as type IIa, with two optically polished opposite large faces. Four samples were implanted with 180 keV B ions, at the Olivetti I-Jet facilities in Arnad (Aosta, Italy).
