Abstract 3D metal printing process has attracted increasing attention in recent years due to advantages, such as flexibility and rapid prototyping. This study aims investigate the orientation effect of electropolishing characteristics on different surfaces 316L stainless steel fabricated by laser powder bed fusion (L-PBF), considering that rough surface printed parts is a key factor limiting it...

PURPOSE The aim of the presented research was to find a combination of surface modification methods of implants made of the Ti-6Al-4V ELI alloy, that lead to formation of effective barrier for metallic ions that may infiltrate into solution. METHODS To this end, the following tests were carried out: roughness measurement, the voltamperometric tests (potentiodynamic and potentiostatic), and th...

Electropolishing is one of the most widely applied metal polishing techniques for passivating and deburring parts. Copper often used as cathode electrode electropolishing due to its low electrical resistance flow values. However, during process, elution caused by electrolyte remaining oxygen gas also causes critical water pollution inhibits efficiency. Therefore, achieve an efficient eco-friend...

The processes of creating a superconducting niobium coating on cryogyroscope rotor were considered. conditions for the electrodeposition coatings from molten salt rotors cryogenic gyroscope determined. Niobium obtained electrochemically polished and subsequently protective pentoxide was electroformed. occurring during electrodeposition, electropolishing electrooxidation equipment technology dev...

Grey relational analysis is useful for the multi-input, discrete data and uncertain experimental study. Developed in this paper is the application of the grey relational analysis for optimizing the electropolishing of 316L stainless steel with multiple performance characteristics. The processing parameters (temperature, current density, and electrolyte composition) are optimized with considerat...
