Currently, many medical devices are made of implantable metals such as 316LVM stainless steel. Electropolishing is a common process to obtain a smooth surface, free of contaminants and more passive, which allows for minimizing the foreign body response and cell adhesion. However, polishing of small implants with a highly complicated geometry and nonuniform metallurgy might result in unsatisfact...

Electrolyte additives, applied voltage, and wiping speed were investigated to elucidate the optimum conditions for electropolishing of stainless steel（SUS304）using a method with an electrolyte-solution-impregnated felt wiper cathode. Adding viscosity improver surfactant electrolyte solution（mixed acid 98% sulfuric 85% phosphoric acid（1 : 3, v/v））reduced evolution pits on electropolished SUS304 ...

Objective: To compare and evaluate the shear bond strength of recycled orthodontic brackets using different methods. Materials & Method: A total of 50 extracted premolars and 50 metal brackets with a slot configuration of 0.022”x0.028” were used. All samples were divided into 5 groups with 10 samples each. Each group was further divided into 2 groups which were control group and experimental gr...

Several surface modification techniques such as ion implantation, surface laser melting, have been employed to improve pitting corrosion resistance of stainless steel. Electropolishing is a technique in which the surface roughness is eliminated through a selective electrochemical dissolution. The effect of electropolishing on pitting corrosion of 304 stainless steel (SS) was investigated employ...

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...

This work presents the nanoindentation and XPS results of a newly-developed biomaterial of titanium TNZ alloy after different surface treatments. The investigations were performed on the samples AR (as received), EP (after a standard electropolishing) and MEP (after magnetoelectropolishing). The electropolishing processes, both EP and MEP, were conducted in the same proprietary electrolyte base...

We have studied the influence of the surface roughness of copper foils on the sheet resistance of graphene sheets grown by chemical vapor deposition. The surface roughness of the copper foils was reproducibly controlled by electropolishing. We have found that the graphene sheet resistance monotonically decreases as the surface roughness of the copper foils decreases. We show that a pre-annealin...

Cu electropolishing was studied using a rotating disc electrode in a variety of phosphoric acid-based electrolytes, including several with ethanol and other species added as diluents. Diluents allow a wider range of water concentrations and electrolyte viscosities to be accessed and also reduce the removal rate during Cu electropolishing, simplifying possible application to damascene processing...
