Dual laser deposition of Ti: DLC composite for implants

Popis výsledku v původním jazyce

Ti-doped hydrogen free diamond-like carbon (DLC) layers of dopation up to 25 at.% were prepared by dual beam pulsed laser deposition (PLD) using two excimer lasers. The arrangement allows continuous fine tuning of dopant concentration on a large scale and deposition flexibility. The layers were prepared on Si(1 0 0) and Ti6Al4V substrates at room temperature. The surface morphology, mechanical properties, bonds, composition, morphology of human osteoblast-like Saos-2 cells, their metabolic activity and production of osteocalcin, a marker of osteogenic cells’ differentiation were tested. The films’ composition changed after x-ray photoelectron spectroscopy (XPS) surface cleaning by argon clusters. Adhesion moved with Ti dopation from 4 N (DLC film) to 11 N (25 at.% of Ti in DLC). Creation of TiC was observed for higher Ti dopation. The contact angle and surface free energy stayed unchanged for higher Ti dopation.
