| Abstract | A novel nanosandwich-structured Ti-B-N coating was prepared on a Ti-6Al-4V substrate using a double glow discharge plasma technique. This coating consists of alternating Ti(N,B) nanocrystalline layers, containing nanoscale growth twins, and amorphous TiB2-BN layers. Compared with a monolithic TiB2.06 nanocrystalline coating, the new Ti B N coating exhibits a marked increase in both damage resistance and hardness (i.e. similar to 55 GPa). The enhanced mechanical properties were found to stem from a combination of nanostructuring and nanotwinning effects. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. |
