Mechanical surface treatments effects on corrosion of AISI 316 Ti stainless steel in chloride environments
TLDR
In this paper, the effects of various surface treatment techniques such as grinding, garnet blasting, and shot peening on the corrosion rate and behavior of austenite stainless steel of type AISI 316 Ti were investigated using immersion tests and electrochemical impedance spectroscopy together with opticalscanning electron microscopy.Abstract:
The current paper investigates effects of various surface treatment techniques suchas grinding, garnet blasting, and shot peening on the corrosion rate and behaviorof austenite stainless steel of type AISI 316 Ti. The exposure to different corrosivesolutions usually accompanying the coastal and industrial environments (sodiumchloride and ferric chloride), as well as a combination of the two was considered. Thecorrosion behavior of AISI 316 Ti under these test conditions was investigated usingimmersion tests and electrochemical impedance spectroscopy together with opticalscanning electron microscopy, in order to observe and to assess the changes in thesurface configuration and topography such the shapes, distribution, and dimensionsof the resulting pits. The presented results clearly show the relatively higher corrosiveeffect of ferric chloride, and the increased corrosion rate under greater surfaceroughness values, which imply greater real surface area and capillarity effects.read more

Tensile properties of a nanocrystalline 316L austenitic stainless steel
TL;DR: In this article, a nanocrystalline 316L austenitic stainless steel sample (mean grain size similar to 40 nm) was prepared by means of surface mechanical attrition treatment, which exhibited an extremely high yield strength up to 1450 MPa, which still follows the Hall-Petch relation extrapolated from the coarse-grained material.

Enhancement of fatigue and corrosion properties of pure Ti by sandblasting
TL;DR: The peak subsurface compressive residual stress produced by sandblasting was measured by XRD to be around 480 MPa as mentioned in this paper, and three distinct regions were observed in the sandblasted samples, namely severely deformed surface layer, the region deformed mainly by twinning, and the substrate.
