Additive manufacturing (AM) of metallic parts is gaining momentum in production industries. In view producing a metal microproduct using AM the issue high surface roughness prominent. Plasma electrolytic Polishing (PeP) post processing technology that greatly reduces parts. this paper effects PeP microfluidic platform, printed with selective laser melting (SLM) technology, presented. The result...

Abstract Additive manufacturing (AM) as a key enabling technology provides new options for engineering design of complex parts. Freeform shapes, grid‐like structures and internal cavities enable functional integration, reducing assembly space requirements increasing reliability. Metal AM technologies, however, require post‐processing in order to achieve acceptable surface roughness ‐functionali...

This study assessed surface treatment techniques applicable to welded joints of stainless steel pipes and vessels for a hydrogen-permeation barrier. Specifically investigated was electrolytic polishing using electrolyte compositions consisting sulfuric acid, phosphoric methane-sulfonic acid promote uniform passive film formation on type 304 surface. also examined oxidation combination chemical ...
