Abstract:

Summary: Cobalt- chromium molybdenum (Co-Cr-Mo) alloys are one of the most useful alloys for biomedical applications such as dental and orthopedic implants because of their excellent mechanical properties and biocompatibility[1?2]. Metallic materials play an essential role in assisting with the repair or replacement of bone tissue that has become diseased or damaged. Metals are more suitable for load bearing applications compared to ceramics or polymeric materials due to high mechanical strength and fracture toughness [3]. However, the main limitation of these metallic materials is the release of the toxic metallic ions that can lead to various adverse tissue reactions and/or hypersensitivity reactions [4]. The main goal of the study was to fabricate nanocomposite coatings based material on dental Co-Cr-Mo alloy with different amounts of Fluorapatite nanopowder, using the pulsed laser deposition and to evaluate bioactivity properties on biological material. The Co-Cr-Mo alloy was purchased from American Elements, USA. The Fluorapatite nanopowder was prepared by mixing calcium hydroxide (Ca(OH)2), phosphorous-pent oxide (P2O5) and calcium fluoride (CaF2) in a planetary high energy ball mill using zirconium vial. In order to prepare cobalt base alloy/ Fluor apatite nanocomposite, the pellet of Co-Cr-Mo alloy covered partially with triangular segments of Fluorapatite. The Fluorapatite powder particles were obtained at approximately 35-65 nm. The pulsed laser deposition. This study showed successful synthesis of Co-Cr-Mo nano-composite coating by PLD.
