Influence of Ultrasound on Corrosion Behavior of SUS304 Stainless Steel with Crevice

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...

Influence of Laser Ablation on Stainless Steel Corrosion Behaviour

Laser ablation is the method for material removing from a surface using pulsed lasers. It is used for surface structuring, laser drilling or laser marking. A change of the corrosion behavior of a base material caused by thermal effects during laser processing is an important problem of this technology. Possibilities of surface modification of stainless steel using laser ablation are presented i...

Suppression of Corrosion Growth of Stainless Steel by Ultrasound

The Effect of Surface Treatment on Corrosion behavior of Surgical 316L Stainless Steel Implant

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...

In-Situ Observation and Acoustic Emission Analysis for Corrosion Pitting of MgCl2 Droplet in SUS304 Stainless Steel

Acoustic emission with near-field detection and optical video microscope monitoring was proposed to investigate the pitting corrosion caused by a small magnesium-chloride droplet. Four types of the detected waveforms were characterized by the wavelet analysis to investigate the corrosion of work-hardened SUS304 stainless steel. After high-activity AE signals observed, the corrosion product shee...
