摘要: Abstract The PVD–TiN film was implanted with titanium and nitrogen ions the improvement in surface wear resistance investigated. Ti ion implantation done using a metal vapor vacuum arc (MEVVA) source an dose of 2 × 10 16  ions/cm 2 at extraction voltage 48 kV. characteristics samples were measured compared performance unimplanted one by pin-on-disc apparatus optical interference microscope. structures observed X-ray photoelectron spectroscopy (XPS) transmission electron microscopy (TEM). A dynamic TRIM called as TRIDYN used to calculate concentration depth profiles TiN investigate mechanisms. results showed that improved mainly due forming nano-order crystal grains thick amorphous layer decreased local state number after implantation.
