Passivity of AISI 316L stainless steel as a function of nitric concentration

Micro 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...

Biomaterial 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...

Passivation and corrosion behaviours of AISI 316L stainless steel as implant materials in simulated blood environment

The purpose of the study was evaluation of corrosion resistance of steel 316L used in cardiologic treatment mainly for vascular stents. The study analysed influence of electrochemical and chemical treatment of the steel surface, including sterilisation with pressurised water steam, on its corrosion characteristics. The tests were performed in artificial blood plasma simulating human blood envir...

Corrosion Behaviour of Nickel Coated AISI 316 Stainless Steel as a Function of Annealing Temperature

AISI 316 stainless steels were coated with 250 nm Ni film by electron beam deposition and post-annealed at different temperatures with a nitrogen flow of 600 cm3min-1 nitrogen. The prepared samples were corrosion tested in 1.0 M sulphuric acid solution using potentiodynamic technique. Crystallographic and morphological structure of the samples were analyzedanalysed by X-ray diffraction (XRD) an...

Formation of Surface Nano/Ultrafine Structure using Deep Rolling Process on the AISI 316L Stainless Steel

Austenitic stainless steels (ASSs) have an excellent corrosion resistance but relatively-low hardness and yield strength [1,2], leading to limited usage in applications that high values of hardness and wear resistance is necessary for material surface. Therefore, surface properties such as hardness must be improved using appropriate techniques. Mechanical surface treatments such as ultrasonic s...
