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 ...

in the present study, the corrosion behavior of aisi 347 austenitic stainless steel to astm a335 low alloysteel dissimilar joint was investigated. for this purpose, two filler metals, er309l and ernicr-3, were selected to be used during the gas tungsten arc welding process. to investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solut...

deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the finaltempering treatment to enhance the wear resistance and hardness of the steels. in this study, the effects of thedeep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studiedusing the wear testing machine and polarization and impedance...

In this study, corrosion behavior of copper that was deformed by Simple Shear Extrusion (SSE) method was investigated in 3%wt NaCl solution. Modified Williamson-Hall method, applied on the X-ray diffraction patterns of the samples, showed that increase in the number of SSE passes led to increasing in the dislocation density in the copper samples. Moreover, such deformed samples exh...

The high strength carbon steels such as API X65 is widely used to build the pipelines. In this study, the corrosion behavior welds region of the gas pipeline was studied. For this purpose, Shield Metal Arc Welding (SMAW) was used to evaluate the proposed method. The welding processes were performed with E6010, E6013, and ER70S-6 electrodes as filler metal and welding carried out in 3 passes by ...

The effect of repeated repair welding, shielded with argon, on microstructural properties, corrosion resistance, and dry sliding wear behavior of aluminum alloy 5083/H116 were investigated. Samples were welded by metal inert gas welding method. 100% argon was used to protect fusion zone. Aluminum alloy 5356 was used as the filler metal. The samples for microstructure, corrosion, and wear tests ...

The electrochemical corrosion behavior of a silver-plated circuit board (PCB-ImAg) in a polluted marine atmosphere environment (Qingdao in China) is studied through a simulated experiment. The morphologies of PCB-ImAg show some micropores on the surface that act as the corrosion-active points in the tests. Cl- mainly induces microporous corrosion, whereas SO₂ causes general corrosion. Notably, ...
