Nanoparticles TiO2: Ag thin films coated stainless steel 316L by R.F. magnetron sputtering technique for anticorrosion in simulated body fluid (SBF)

In this research, TiO2 nanoparticles were prepared using the Sol-Gel method and mixed with different addition concentration of (3,5and7)% ww Ag nanoparticles for TiO2: Ag and obtained different thickness on the base used (Stainless 316L). These films were placed in an oven (600 ° C) for one hour to...

Description
Summary:In this research, TiO2 nanoparticles were prepared using the Sol-Gel method and mixed with different addition concentration of (3,5and7)% ww Ag nanoparticles for TiO2: Ag and obtained different thickness on the base used (Stainless 316L). These films were placed in an oven (600 ° C) for one hour to improve the crystallization structure of thin films. The AFM, SEM, EDX and XRD inspections revealed useful data on particle size, shape, surface elemental, and the structure. (AFM,SEM, X- ray, EDS) tested and showed that the minimum particle size was (35 nm) for TiO2: Ag at 7% of silver and corrosion in stainless steel in SBL using the electrochemical method (Tafel curves). All samples achieved excellent results to reduce corrosion but at different rates was the best result TiO2:Ag 3%
