COMPARISON OF WEAR RESISTANCE MECHANISMS OF DIE STEEL IMPLANTED WITH C AND Mo IONS

CHENG, M. F.; YANG, J. H.; LUO, X. D.; ZHANG, T. H. - In: Surface Review and Letters (SRL) 14 (2007) 03, pp. 517-520

Mo and C ions extracted from a metal vapor vacuum arc ion source were implanted into the surface of die steel (H13) to compare the wear resistance mechanisms of the implanted samples, respectively. The concentration depth profiles of implanted ions were measured using Rutherford backscattering...

CHARACTERIZATION OF SURFACE PROPERTIES AND MICROSTRUCTURE OF PVD-TiN FILMS USING MEVVA ION IMPLANTATION

YANG, J. H.; CHENG, M. F.; LUO, X. D.; ZHANG, T. H. - In: Surface Review and Letters (SRL) 13 (2006) 04, pp. 519-524

The PVD-TiN film was implanted with titanium ions and the improvement in surface wear resistance was investigated. Ti ion implantation was done using a metal vapor vacuum arc (MEVVA) ion source with an implantation dose of 2 × 1016 ions/cm2 and at an extraction voltage of 48 kV. The wear...
