摘要: Abstract The aim of this work was to investigate the electrochemical and repetitive impact wear behaviors Cr- Al-doped TiSiCN coatings in comparison with their TiCN counterparts. were deposited by reactive DC magnetron sputtering TiC, TiSiC, TiCrSiCN, TiAlSiCN targets a gaseous mixture Ar + 15%N 2 . structure, elemental phase compositions studied means X-ray diffraction, scanning electron microscopy, glow discharge optical emission spectroscopy. characterized terms hardness, elastic modulus, recovery, adhesion strength. To evaluate characteristics, tested 1N H SO 4 0.9% NaCl solutions. also subjected range tests, first air, then normal saline (to assess tribocorrosion effect) distilled water hydrodynamic effect liquid). obtained results show that all coatings, except TiCN, exhibit similar mechanical properties but failure modes (plastic deformation, brittle fracture or combinations) during scratch tests are markedly different. poorest dynamic performance coating water, solution attributed both imperfection structure (micro-chips “pin-holes”) reduced properties. Although possessed highest its high led resistance. Cr-doped performed well rapidly failed due corrosion reactions. only one which sustained load for 10 5 cycles air (maximal 1000 N), as (neutral medium) (corrosive at 500 N.
