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 کاملThe Inhibition Effect of Polyethylenimine (PEI) on Pitting Corrosion of 304 Austenitic Stainless Steel in 3.5% NaCl Solution
One of the problems in the case of stainless steels is their low corrosion resistance against pitting corrosion in chloride containing environments, thereby leading to severe damage to industries. In this research, the pitting corrosion of 304 austenitic stainless steel was studied in 3.5% NaCl solution at room temperature (25˚C) by performing electrochemical measurements (containing cyclic pol...
متن کاملStudy of the Corrosion Resistance of Type 304L and 316 Austenitic Stainless Steels in Acid Chloride Solution
The corrosion resistance of type 304L and 316 austenitic stainless steels in 2M H2SO4 at 0-1.5%NaCl concentrations was studied through potentiodynamic polarization technique and optical microscopy analysis. The corrosion rate, pitting potential, passivation potential and surface morphology of both steel where significantly altered by the Clion concentration, alloy composition and metallurgical ...

متن کاملA Corrosion Study of Grain-Refined 304L Stainless Steels Produced by the Martensitic Process
AISI 304L austenitic stainless steel with different grain sizes of 0.5 -12 μm was obtained through the martensitic process. Corrosion behavior of different samples was investigated in a 0.5M HCl solution using open circuit potential, potentiodynamic polarization and electrochemical impedance spectroscopy tests. Also, the correlation between the grain size and pitting corrosion resistance was as...
