The aim of the present work was to study passive film stability and pitting corrosion behavior AISI 409 stainless steel. electrochemical tests were carried out in 0.1 M NaCl solution at room temperature. general assessed using impedance spectroscopy (EIS) measurements whereas semiconducting properties evaluated by Mott-Schottky approach. Pitting investigated potentiodynamic potentiostatic polarization tests. Surface morphology examined confocal laser scanning microscopy electron (SEM)....
Global and local corrosion techniques were used to study the behavior of weld joints a high-strength low-alloy steel (LNE500) typically in automotive industry Brazil. The welded prepared by gas metal arc welding. Two welding transfer modes obtain different heat inputs: pulsed (PUL) cold (CMT). Local global analysis presented complementary information. While situ (scanning vibrating electrode technique) revealed (WM) as region where started, conventional electrochemical (potentiodynamic...
The correlation between the surface chemistry and corrosion behavior of quaternary CuAlMnGd CuAlMnSn alloys was studied in 3.5 wt.% NaCl solution. were produced by arc furnace melting. Sn addition promoted formation a homogeneous microstructure, while different crystalline phases are formed Gd-containing alloy. immersed electrolyte for 48 h. X-ray photoelectron spectroscopy (XPS) revealed that Gd is present as Gd2O3 and/or Gd(OH)3 on film After immersion sodium chloride solution, became...
We studied the real time effects of gamma radiation in ceramic capacitors, order to evaluate cosmic on these devices. Space missions have electronic circuits with various types devices, many studies been done semiconductor devices exposed radiation, but almost no for passive components, particular capacitors. Commercially sold capacitors were and capacitance was measured before after exposure. The results clearly show that decreases exposure radiation. confirmed this observation a...
