| Abstract [eng] |
The properties of inorganic materials are mainly determined by their composition, structure, morphology. Materials such as chromium (III) oxide (Cr2O3) coatings and nanoparticles have received great attention due to its wide range of applications: super capacitor, liquid vibration sensors, pigments, heterogeneous catalysts. Especially there is a need of these coatings on a regular basis in medical industry. Cr2O3 is used in orthopedic implants because it eliminates the risk of chromium ion release into the patient as well as antimicrobial and antibacterial coatings [1]. Titanium alloys and stainless steel alloys have biocompatibility issues and are not immune to wear and corrosion. For instance, stainless steel implants show deterioration of the material, resulting in the release toxic for human body system Fe, Cr and Ni ions [2]. Chromium oxide coatings can be prepared using various techniques such as laser deposition, sputtering, sol-gel, solid thermal deposition, chemical vapour deposition, plasma spray pyrolysis [3]. In this work reactive magnetron sputtering was used and it is considered as the most preferable synthesis method for mass production. This technique allows the formation of high quality Cr2O3 coatings with desired properties for medical applications. Cr2O3 coatings were prepared in situ reactive magnetron sputtering at 500 °C in oxygen environment. The resulting Cr2O3 films were characterized by X-ray diffraction (XRD), UV-visible absorption. |
