This paper is an attempt to synthesize nanostructured tantalum films on medical grade AISI 316L stainless steel (SS) using pulsed DC plasma assisted chemical vapor deposition (PACVD). The impact of duty cycle (17-33%) and total pressure (3-10 torr) were studied using field emission scanning electron microscopy (FESEM), grazing incidence x-ray diffraction (GIXRD), nuclear reaction analysis (NRA)...

in order to increase the life span of implants, coatings such as bioglass are applied on implants' surfaces to prevent their corrosion in biological fluids. in this research, 45s5 bioglass coatings were applied on 316l stainless steel substrate by sol- gel method and coating's properties were examined by different analyses. according to the xrd results, an amorphous compound containing na2ca2si...

Volume 3 • Issue 4 • 1000e108 J Nanomed Nanotechol ISSN:2157-7439 JNMNT an open access journal For centuries, metals and alloys have been used in substitution for anatomical structures owing to their extraordinary mechanical properties [1]. Type 316L Stainless Steel (SS) is known to be widely used for implantation purposes in orthopedic surgery due to its corrosion resistance, effective cost an...

The AISI 316 L Stainless Steel (SS) specimens were exposed to passivation surface through two different processes including; holding in 40-vol% HNO3 at temperature of 60 ºC for 30 min and 15-vol%H2SO4 at ambient temperature for 1 hour. The corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear an...

Nanohydroxyapatite-carbon nanotube composite coatings were deposited via electrophoretic deposition (EPD). AISI 316L stainless steel and ethanol were used as substrate and dispersing medium, respectively. 5%wt carbon nanotube (CNT) was used as reinforcing phase. Uniform and macrocrack-free coatings were obtained both for hydroxyapatite (HA) and HA-5%wt CNT coatings. Scanning electron micros...

Nanohydroxyapatite-carbon nanotube Nanocomposite (HA-CNT) coatings were deposited via electrophoretic deposition (EPD). Hydroxyapatite was synthesized via microwave combustion method using calcium nitrate and glycing as starting materials. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) revealed that pure hydroxyapatite nanoparticles have been synthesized. AISI 316L s...

The corrosion behavior of TiN coated 316L stainless steel in an artificial physiological solution was investigated by means of an electrochemical test. Two different PVD methods were used for film deposition: cathodic arc and reactive magnetron sputtering. The dependence of the corrosion resistance on the main deposition parameters (nitrogen pressure, substrate bias) was analyzed. For a better ...

In this paper we study the corrosion of AISI 304 austenitic stainless steel PEMFC bipolar plates in aqueous and room-temperature ionic-liquid electrolytes. The anodic potential thresholds and dynamics have been investigated by electrochemical (potentiodynamic and potentiostatic) and in situ spectroelectrochemical methods (visible electroreflectance and VIS-UV spectroellipsometry). We measured t...

OBJECTIVE To determine the microchemical and surface composition of tibial plateau leveling osteotomy (TPLO) plates before and after explantation. SAMPLE POPULATION 7 TPLO plates surgically removed from host dogs 6 to 54 months after implantation; 2 raw unpolished-and-unpassivated 316L TPLO plates; and 2 heat-treated, polished-and-passivated, and cleaned 316L TPLO plates. PROCEDURES Samples...
