Biological and tribological study of diamond-like carbon doped by titanium prepared by hybrid laser technology

Popis výsledku v původním jazyce

Diamond-like carbon (DLC) films are broadly studied for many purposes in many branches. For improvement of their mechanical properties and biocompatibility many deposition techniques and dopants were tested. This study is focused on changes in mechanicalbehaviour and biocompatibility with various amount of titanium in DLC thin films. Used technique is based on pulsed laser deposition (excimer laser, KrF, ? = 248 nm) combined with DC magnetron sputtering. Range of laser fluencies was from 3 to 8 J/cm2,power of magnetron was from 25 to 200 W. We studied behaviour of layers for low Ti concentration from as 1at% to 10at%. Si(100) and Ti6Al4V alloy were used as substrates. Prepared films were characterized with focus on their basic properties, such as crystallinity by XRD, morphology by AFM and profilometry, chemical bonding nature by WDX, wettability and surface free energy by contact angle. Hardness, Young's modulus and microadhesion were studied by nanoindentation. Makro adhesion was s
