A method to electropolish niobium with continuous current oscillation is introduced. The current continuously oscillates for as long as 3 hours. The key is to maintain continuous agitation of the acid mixture. A niobium surface treated by this method has suppressed grain boundaries and a lower hydrogen content. The method has been used to electropolish L-band half-cells. The test results of a 1...

The reduction of surface roughness on additively manufactured components has become a critical factor in engineering applications. This paper reports the electropolishing Ti-6Al-4V by powder bed selective laser melting (SLM) using nontoxic electrolyte solution. results have shown that salt-based can be used to electropolish titanium alloys. waviness as-built alloy was reduced five times average...

In 19 10 S P I T A L S K Y ( 1 ) described, in a Germ an patent then granted, an electro­ lytic process which imparted to silver a highly increased lustre in the course of a few minutes. This, according to the description of the process, constitutes the first known exam ple of electrolytic polishing (electropolishing) that has come to the author’s notice. The silver was placed as anode in an al...

PURPOSE Clinical cases of stent-fractures show that corrosion behavior might play a role in these fractures. Implanted in vivo, especially in combination with other implanted foreign materials, these metallic products are exposed to special conditions, which can cause a process of corrosion. Here, we aimed to test the corrosion potential of stents made of different materials in an in vitro sett...

In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with 1) no polishing process (A sample), 2)electropolishing process (B sample) and 3) electropolishing process in ethanolicelectrolyte (C sample). To study the ...

types of capacitor construction and effects on power loss and power dissipation. Outline ways to manage power loss, with emphasis on the capacitors Equivalent Series Resistance (ESR). Review the key elements for modeling the capacitor by applying S2P files for impedance calculations.
