1Effect of Surface Treatment and Metallic Coating on Corrosion Behavior and Biocompatibility of Surgical 316L Stainless Steel Implant显示文摘Surface engineering technology is a suitable method for coatings on the metal surfaces or performing surface modification treatment,which can improve corrosion resistance and biocompatibility of metals.In this research,corrosion behavior of Nb coating on H 2 SO 4 and HNO 3 treated AISI stainless steel 316L (SS) was evaluated.Nb coating was carried out using physical vapor deposition process on the SS.Characterization techniques including scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) technique were used to investigate the microstructure and morphology of the coated and treated SS.Electrochemical potentiodynamic tests were performed in two types of physiological solutions and compared with the pristine SS specimens.Cyclic polarization tests were performed to evaluate resistivity against pitting.Experimental results indicate that Nb coating and surface treatment of the SS had a positive effect on improvement of corrosion behavior.The decrease in corrosion current densities was significant for coated and treated specimens.The corrosion current density was much lower than the values obtained for pristine specimens.Ali Parsapour Saied Nouri Khorasani Mohammad Hossein Fathi 2012Journal of Materials Science & Technology2012,28,2:2

5Corrosion Behavior and Biocompatibility of Hydroxyapatite Coating on H_2SO_4 Passivated 316L SS for Human Body Implant显示文摘The aim of this studies at simultaneous improvement of the corrosion behavior and biocompatibility of metallic implant and bone Osseointegration simultaneously.Stainless steel 316L(SS) was used as metallic substrate and after surface treatment with 15 vol.% sulfuric acid,it was coated with hydroxyapatite coating employing plasma-spraying process.Structure characterization techniques including XRD,SEM and EDX were also utilized to investigate the microstructure,morphology,and crystallinity of the coating.Electrochemical potentiodynamic tests were performed in two types of physiological solutions in order to determine and compare the corrosion resistance behavior of the coated and uncoated specimens as an indication of biocompatibility.The results indicate that the surface treatment and hydroxyapatite coating improve the corrosion resistance behavior of SS.The corrosion current density of the surface treated and the hydroxyapatite coated SS also decrease.These also show that surface treated and hydroxyapatite coated SS can be used as human body implants with the goals of corrosion resistance improvement(biocompatibility) and bone osseointegration.Ali Parsapour Saied Nouri Khorasani Mohammad Hossein Fathi 2013Acta Metallurgica Sinica(English Letters)2013,26,4:0
