Abstract EN
Biomedical alloy 316L stainless steel enhancing to replace biological tissue or to help stabilize a biological structure, such as bone tissue, enhancing were coated with deposition a thin layer of silver nanoparticles as anti-bacterial materials by using DC- magnetron sputtering device.
The morphology surface of The growth nanostructure under the influence of different working pressure were studied by atomic force microscope.
The average grain size decrease but roughness of the silver thin layer was increased with‖ ―increasing the working pressure.
The thickness of silver thin layer was increased from 107 nm at 0.08 mbar to 126 nm at 1.1 mbar.
Antimicrobial activity of silver thin layers at different working pressure were studied.
The results showed that the increasing in working pressure, lead to increase in activity of silver thin coating layer against the bacteria as a result of increasing in thickness and‖ roughness of thin coating layer.
This work has been extended to study the anti-bacterial activity were fount the diameters of inhibition zone of gram positive bacteria between 16.5±1.5 and 19±0.5 while the diameters of inhibition zone of gram positive bacteria between 17±1 and 26±1.
Finally the measurements of the 316L alloy coated by silver nanocoating layer after immersing the in simulated body fluid (SBF) solution for one month is the XRD pattern for the sample showed obviously that the Hydroxyapatite layer was appeared at (2= 31.8).
