  • Adhesion enhancement of diamond coatings on WC tools by high energy ion irradiation 

    Dilawar, Nita; Kapil, Rahul; Vankar, V D; Avasthi, D.K.; Kabiraj, D; Mehta, G K (1998)
    Microcrystalline diamond thin films were deposited on cemented tungsten carbide cutting tools by hot-filament chemical vapour deposition process. The coatings deposited were irradiated with 50 MeV Si7q ions upto a dose of ...
  • Radiation hardness of polycrystalline diamond thin films irradiated with 100 MeV I7+ ions 

    Dilawar, N; Kapil, R; Vankar, V D; Avasthi, D K; Kabiraj, D; Mehta, G K (1997)
    Polycrystalline diamond thin films grown by hot-filament chemical vapour deposition (CVD) process were irradiated with 100 MeV I7+ ions. The as-deposited and irradiated films were characterized using micro-Raman spectroscopy, ...
  • Simultaneous detection of light elements by ERDA with gas-ionisation/Si ΔE-E detector telescope 

    Avasthi, D K; Kabiraj, D; Bhagwat, A; Mehta, G K; Vankar, V D; Ogale, S B (1994)
    Elastic Recoil Detection Analysis (ERDA) using ΔE-E telescope with gaseous ΔE detector is carried out for the first time for simultaneous detection of H alongwith other light elements C, N, and O in Diamondlike Carbon (DLC) ...
  • Study of Hydrogen in DLC Film by ERDA with 58Ni Ions 

    Avasthi, D K; Kabiraj, D; Jaipal; Mehta, G K; Barshilia, H C; Sah, Somna; Mehta, B R; Vankar, V D (1995)
    The content of hydrogen and its depth profile in diamond like carbon (DLCI films deposited by the microwave plasma deposition technique is determined by Elastic Recoil Detection Analysis (ERDA) using 85 MeV 58Ni ions. ...
