Effect of Crystallographic Orientation on the Pitting Corrosion Resistance of Laser Surface Melted AISI 304L Austenitic Stainless Steel
The localized corrosion behavior of laser surface melted 304L austenitic stainless steel was studied by potentiodynamic polarization test. The extent of improvement in corrosion resistance was governed by the preferred orientation and the percentage of delta ferrite present on the surface of the laser melted sample. It was established by orientation imaging microscopy that the highest pitting p...
متن کاملMartensitic Transformation in Ultrafine-Grained Stainless Steel AISI 304L Under Monotonic and Cyclic Loading
The monotonic and cyclic deformation behavior of ultrafine-grained metastable austenitic steel AISI 304L, produced by severe plastic deformation, was investigated. Under monotonic loading, the martensitic phase transformation in the ultrafine-grained state is strongly favored. Under cyclic loading, the martensitic transformation behavior is similar to the coarse-grained condition, but the cycli...
متن کاملSurface characterization of austenitic stainless steel 304L after different grinding operations
Background: The austenitic stainless steel 304L is widely used as a structural material for which the finished surface has significant effect on the service performance. A study of the grinding process with regard to the quality of the ground surfaces is therefore interesting from the point of view of both industrial application and scientific research. Method: This work investigates the influe...
متن کاملBiomaterial Studies on AISI 316L Stainless Steel after Magnetoelectropolishing
The polarisation characteristics of the electropolishing process in a magnetic field (MEP – magnetoelectropolishing), in comparison with those obtained under standard/conventional process (EP) conditions, have been obtained. The occurrence of an EP plateau has been observed in view of the optimization of MEP process. Up-to-date stainless steel surface studies always indicated some amount of fre...
متن کاملXPS Analysis of Passive Film on Stainless Steel
Potentiodynamic, impedance measurements were carried out on 304 stainless steel in 0.5N, 1.0, 2.0 and 5.0 N H2SO4 solutions. X-ray photoelectron spectroscopic [XPS] studies carried out on 304 stainless steel in H2SO4 solutions revealed the existence of CrOOH, Cr2O3, -Fe2O3, FeOOH, Mn2O3, Mn3O4, MnS, Ni (OH)2, Ni2O3, NiO, sulphides. The passive film found to contain chromium oxide inner layer an...
