Corrosion Behaviour of Cardiovascular Stents
Cyclic Potentiodynamic polarization studies were conducted to compare the corrosion resistance of Nitinol cardiovascular stents and stainless steel stents. The tests is to simulate the corrosion behavior of the stents under body condition using Phosphate Buffered Saline (PBS) solution at 37C and following the ASTM F2129-01, Item 2, WK1749, Standard. The results of this study indicate that both ...
متن کاملCorrosion Behaviour of NIMONIC-90 Alloy
Investigations were conducted on hot corrosion of Nickel base, NIMONIC-90 at 675°C and 725°C. The tests were carried out on small test coupons coated with a chemical containing Sodium sulphate and Sodium Vanadate which is representative of the corrosive deposit that usually forms during service in the coal fired boiler and the likes operating in marine atmospheres. Corrosion rates were measured...
متن کاملPitting Corrosion Behaviour of New Corrosion-Resistant Reinforcement Bars in Chloride-Containing Concrete Pore Solution
In this study, the pitting behaviour of a new corrosion-resistant alloy steel (CR) is compared to that of low-carbon steel (LC) in a simulated concrete pore solution with a chloride concentration of 5 mol/L. The electrochemical behaviour of the bars was characterised using linear polarisation resistance (LPR) and electrochemical impedance spectroscopy (EIS). The pitting profiles were detected b...
متن کاملConsequence of Corrosion on Dynamic Behaviour of Steel Bridge Members
Deterioration of steel bridge infrastructures constitutes a major worldwide problem in transportation engineering and maintenance management industry. Corrosion and fatigue cracking may be the two most important types of damage in aging structures. Various kinds of failures and the need of expensive replacements may occur even though the amount of metal destroyed is quite small. One of the majo...
متن کاملCorrosion 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...
