Antibacterial effect of Au implantation in ductile nanocomposite multilayer (TiAlSiY)N/CrN coatings

ACS Applied Materials and Interfaces 2019, 11, 51, 48540–48550 doi:https://pubs.acs.org/doi/10.1021/acsami.9b16328

Gold ions were implanted into a nanoscale (TiAlSiY)N/CrN antibacterial nanostructured layer material.  This process formed local amorphous clusters which significantly enhanced the antibacterial properties of the surface.  Secondary Ion Mass Spectrometry using the SIMS Workstation, was one of the methods used to characterize the structure.  SIMS has a very high sensitivity and excellent depth resolution as well as requiring very little sample preparation.
