چکیده
In the present study we performed anodization of stainless steel AISI 316L varying voltage, time and H 2 O concentration in electrolyte obtaining self-ordered porous oxides. Open-circuit potential measurements, potentiodynamic polarization electrochemical impedance spectroscopy were 0.1 M SO 4 , NaCl NaOH electrolytes. The metallic substrate underneath grown oxide was also characterized. results indicate that corrosion behavior is not impaired by treatments. However, “crevice-induced intergranular corrosion” between revealed after measurements acidic electrolyte.

Corrosion Behavior of Stainless Steel Clad Rebar
Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...
متن کاملOptical Reflection Spectroscopy of Thick Corrosion Layers on 304 Stainless Steel
Corrosion resistant structural materials of both iron and nickel based alloys are used in the electric power industry for the construction of the coolant loops of both conventional and nuclear power generating stations. These materials, in the presence of high temperature (e.g. 287° C), high pH (e.g. 10.0 @ 20°C) water with dissolved hydrogen will oxidize and form corrosion films that are doubl...
متن کاملCorrosion at Sulphide Inclusions in Stainless Steel
Auger analysis was performed using a high resolution scanning auger electron microscope and auger electron spectroscopy. Elemental auger contour maps for corroded sulphide inclusions in stainless steel were presented. It was found that the copper enriched-manganese sulphide inclusions were uniformly corroded, which might be due to CU2S deposition on the surface of corroding inclusions. In contr...

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...
متن کاملSelf-ordered anodic aluminum oxide formed by H2SO4 hard anodization.
The self-ordering of nanoporous anodic aluminum oxide (AAO) in the course of the hard anodization (HA) of aluminum in sulfuric acid (H2SO4) solutions at anodization voltages ranging from 27 to 80 V was investigated. Direct H2SO4-HA yielded AAOs with hexagonal pore arrays having interpore distances D(int) ranging from 72 to 145 nm. However, the AAOs were mechanically unstable and cracks formed a...
