the increase of Cl-concentration of corrosion solution, the fracture mode of 316L stainless steel changes from ductile fracture to brittle fracture, and the corrosion sensitivity increases.
CORROSION FATIGUE CRACK INITIATION BEHAVIOR OF The CF experiments were conducted under the conditions of electrochemically accelerated, free immersion and pre-polarized pitting potential. The results showed that 316L stainless steel was susceptible to pitting corrosion in Hank's solution.
Jan 24, 2013 · Abstract. In oil and gas production environments, H 2 S and Cl can coordinate to cause pitting or stress corrosion cracking (SCC) of stainless steels. There has been limited work conducted on corrosion and SCC of autenitic stainless steels in high H 2 SCO 2 Cl environments. In this paper, by four-point bending test method and scanning electron microscopy analysis, SCC of 316L steel was investigated under high H 2
Corrosion behavior and biocompatibility of additively Aug 01, 2020 · 316L stainless steel (SS) has been used for a long period as a metallic biomaterial for orthopedic implants to make artificial joints, bone plates, screws, and nails due to its reliable combination of biocompatibility, excellent mechanical properties, reasonable corrosion resistance, and cost . However, one of the major limitations of 316L SS as an implant material is its susceptibility to localized corrosion.
Corrosion behavior of additively manufactured 316L and development of rened sub-granular structure in AM 316L stain- less steel can hypothesize its enhanced resistance to corrosion in acidic environment. There have been a limited number of studies in the literature, report- ing the corrosion behavior of AM 316L stainless steel [41,43,44]. This study is elucidating the preliminary results about the corrosion response
The pitting behavior of 316L stainless has been studied by pitting potential measurements using a potentiodynamic test method. The effects of chloride ion concentration, pH, sulfate ion concentration, and temperature of the electrolyte on pit initiation in 316 stainless steel have been determined.
IET Digital Library:Investigation in the corrosion Corrosion resistance of nanocrystalline 316L stainless steel was compared with a coarse-grained (CG) one using potentiodynamic polarisation and electrochemical impedance spectroscopy methods and electron microscopy. The results showed that the corrosion resistance of nanocrystalline 316L stainless steel was higher than CG stainless steel. It was attributed to unstable passive layer on CG 316L
Influence of Ethanol on Pitting Corrosion Behavior of Jun 24, 2020 · The corrosion rate of 316L stainless steel first increased then decreased while the initiation of pits is facilitated. The pitting potential of 316L stainless steel samples in 1 M NaCl solutions decreased from 489 to 239 mV with the gradual addition of ethanol.
This study aims to investigate the effect of the presence of a simulated corrosive body fluid (Hanks solution) on the micro-abrasion and corrosion resistance of two borided biomedical alloys (AISI 316L stainless steel and ASTM F1537 CoCrMo alloy) when in sliding contact with a ceramic countersurface. The materials were subjected to a powder-pack boriding treatment.
The influence of static stress on the corrosion behavior The influence of static stress on the corrosion behavior of 316L stainless steel in Ringer's solution. Bundy KJ, Vogelbaum MA, Desai VH. The decrease in corrosion resistance of 316L stainless steel due to static stress was studied in vitro using a 37 degree C Ringer's solution electrolyte.Corrosion Behaviour of Type 316L Stainless Steel in Hot Oct 20, 2019 · The corrosion behaviour of type 316L stainless steel in aqueous 3050 wt%. NaOH at temperatures up to 90 °C has been elucidated. Exposure to room temperature environment showed parabolic weight loss behaviour, with corrosion rates of up to 0.4 mm/year.
