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 کاملMicro abrasion-corrosion of AISI 316L stainless steel
In this study, the synergistic effects of abrasion and corrosion on AISI 316L stainless steel have been investigated using a micro-abrasion test rig. A series of results from abrasioncorrosion tests conducted using the micro-abrasion rig are presented. AISI 316L stainless steel has been studied under both pure abrasion and abrasion-corrosion conditions simulated by either distilled water or 3.5...
متن کاملIMPROVING PITTING CORROSION OF 304 STAINLESS STEEL BY ELECTROPOLISHING TECHNIQUE
Several surface modification techniques such as ion implantation, surface laser melting, have been employed to improve pitting corrosion resistance of stainless steel. Electropolishing is a technique in which the surface roughness is eliminated through a selective electrochemical dissolution. The effect of electropolishing on pitting corrosion of 304 stainless steel (SS) was investigated employ...
متن کاملInfluence of Laser Ablation on Stainless Steel Corrosion Behaviour
Laser ablation is the method for material removing from a surface using pulsed lasers. It is used for surface structuring, laser drilling or laser marking. A change of the corrosion behavior of a base material caused by thermal effects during laser processing is an important problem of this technology. Possibilities of surface modification of stainless steel using laser ablation are presented i...
متن کاملStrain-Induced Martensite Transformation Simulations during Cold Rolling of AISI 301 Austenitic Stainless Steel
Austenite is a semi-stable phase in most stainless steels that deforms to martensite under Md30 and forms martensitetype ά and ε due to the deformation in the steels. Since the distribution of strain induced martensite plays animportant role in achieving desired properties, the main objective of the present work is to model martensitedistribution of ά during cold rolling using...
