This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Metal additive manufacturing techniques have been recognized for their capability of controlling the crystallographic orientations of stainless steels. However, the inherent anisotropic corrosion behaviors have not been extensively explored. In this study, the corrosion properties of 316L stainless steels prepared by Laser Powder Bed Fusion (LPBF) additive manufacturing were investigated. The effects of different crystallographic textures, namely {100}, {110} and {111} on both general and pitting corrosion were characterized by several electrochemical measurements, including Electrochemical Impedance Spectroscopy (EIS), potentiodynamic polarization and Mott-Schottky analysis. The results were also compared to the polycrystalline and wrought 316L counterparts. It was found that the {111} sample offered the highest general corrosion resistance, followed by the {100} and {110} samples. The origin of this trend was related to the surface atom density. The {111} surface exhibited a stronger atomic bonding than that of {100} and {110} samples, resulting in a higher corrosion activation energy and thus a higher general corrosion resistance. The LPBF samples also offered a significantly higher pitting corrosion resistance, which was attributed to the lower concentration of oxygen vacancies (donor levels) in the passive film that serve as pits nucleation sites, as observed by the Mott-Schottky analysis"--

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The pitting corrosion behavior of 301, 304 and 316 austenitic stainless steels in 2M H2SO4 at 0-1.5% NaCl concentrations was investigated through potentiodynamic polarization and optical microscopy analysis. Electrochemical analysis of the pitting corrosion inhibition and surface protection properties of rosemary oil and aniline on the stainless was also performed. The corrosion rate, pitting potential, passivation potential, metastable pitting potential and surface morphology of both steels where significantly altered by changes in chloride concentration, differences in alloy composition and metallurgical properties of the steels. 316 steel had the lowest corrosion rate and highest pitting corrosion resistance followed by 301 steel. The surface morphology of 316 steel was slightly altered at 1.5% NaCl concentration while 301 steel appears to etch with grain boundaries appearing at higher chloride concentration. 304 steel showed no resistance to pitting after 0% NaCl coupled with relatively significant increase in corrosion rate values. Its surface morphology showed the presence of corrosion pits with respect to chloride and inhibitor concentration. Rosemary oil and aniline significantly reduced the corrosion rates values of the stainless steels and with consequent increase in their pitting corrosion resistance; however the compounds had no positive influence on the pitting corrosion behavior of 304 steel.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanical and physical properties. Instead alloys, however both materials can be attacked by corrosion which it definitely contributes to the depletion of our natural resources. The main objectives of this study were to observe the corrosion behavior of stainless steel 304 and Aluminum Alloys 6061 under variation of ph and to investigate the effect of ph variation on the surface and microstructure of stainless steel 304 and Aluminum Alloys 6061. This study was conducted by following the scopes of this project includes the sample preparation, cleaning procedure before and after test, exposure to actual condition, surface and microstructure observation using Scanning Electron Microscopy (SEM) and corrosion rate analysis by weight loss method. Under pH variation, there are three types medium of test used include acidic by Nitric Acid, alkaline by Sodium Hydroxide and Neutral by distilled water. Each sample undergoes environmental exposure for a week before the surface morphology investigation was conducted. From the experimental result during test day, there are changes in color medium of test (Nitric acid, Sodium hydroxide and distilled water) when testing both materials under variation of pH. The surface morphology of Stainless Steels and Aluminum Alloys had been observed using SEM for materials characterization. Corrosion rate was determined for all samples. It was found that Aluminum Alloy 6061 posses the highest rate of corrosion; 208.69mpy in acidic (HNO3) followed by alkaline (NaOH); 40.98mpy and lastly neutral (Distilled Water); 29.00mpy.For Stainless Steels 304, the highest corrosion rates occur in medium of Nitric acid which was 35.30 mpy while the lowest corrosion rates occur in medium of distilled water which was 2.05 mpy. The corrosion rate in medium of Sodium Hydroxide was about 7.22 mpy. Any features of corrosion failure give significant clue of the possible corrosion factor. This article details a proven approach to properly determining the effects of the pH variation and material types to the corrosion rate, and includes surface microstructure of the most common corrosion types, including crevice corrosion, pitting, and intergranular. In conclusion, pH variation influence the rate of corrosion. Because of passivation and high chromium contents, it forms a barrier or protective film on the surface and microstructure of AISI 304 thus decrease the corrosion rate compare to AA 6061. Hence, AISI 304 was proves to be the most protective sample and corrosion durable. Also, it may suggest that for engineering application under variation of pH, AISI 304 is highly recommended.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "316L stainless steels (SS) are widely used as biomaterials due to their good general corrosion resistance, low cost and good machinability. However, 316L SS is prone to severe degradation in human body due to aggressive halide ions present in the environment, namely chlorides and bromides, which can cause a local breakdown of the protective passive film and enable the progression of pitting corrosion. Hence, significant efforts have been made to develop methods for the surface modification of the 316L SS in order to improve its pitting corrosion resistance, and thus its biocompatibility.In this work, the application of cyclic potentiodynamic polarization (CPP) for the formation of a highly corrosion resistant passive oxide film on a 316L SS surface using a 0.1 M NaNO3 solution as a passivation electrolyte in deaerated and aerated conditions was investigated. Electrochemical tests such as open circuit potential (OCP) measurement and potentiodynamic polarization test were conducted to evaluate the corrosion behavior of the modified surface. It was found that CPP method under both deaerated and aerated conditions resulted in formation of a passive oxide film that offers significantly higher OCP and pitting corrosion resistance than the naturally-grown passive film. The results of OCP and potentiodynamic polarization tests show that the passive film formed by CPP in an aerated 0.1 M NaNO3 solution exhibits higher OCP and higher pitting corrosion resistance than the film formed in a deaerated 0.1 M NaNO3 solution. It was observed that dissolved oxygen has a positive effect on the passivation of 316L SS under CPP conditions. The 316L SS surface passivated for 200 sweeps in an aerated 0.1 M NaNO3 solution exhibited largest improvements: highest open circuit potential (141.77 mVSCE) and complete elimination of pitting corrosion in a 0.1 M PBS solution at 22 °C.
