چکیده
|
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 ؛c 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 and tafel polarization tests. cyclic polarization tests were performed for investigating of the specimen's resistance against pitting. finally, the corrosion resistance of untreated and modified specimens was compared. the results show that the corrosion resistance of 316l ss metallic implant is increased due to passivation surface treatment.
