Abstract

A study of defect structure in (TiZrHfNbV)N coatings irradiated with 200 MeV high energy Xe14+ ions with different fluences by positron annihilation spectroscopy (PAS) was carried out. Positron lifetime studies showed that the vacancy-defects are the dominant defects type in investigated specimens. Although (TiZrHfNbV)N coatings were irradiated with high energy Xe+ ions with different fluences: 5 × 1011, 5 × 1012 and 5 × 1013 ions/cm2, no amorphous or intermetallic phase are detected.
