In this research, the use of plasma electrolytic polishing (PEP) as a finishing treatment materials obtained by SLM method from CoCr30 cobalt-chromium powder is proposed. To assess possibility using method, simulator sample was used. The imitation polished for 60 seconds. roughness and size removal material were measured. Based on results sample, conclusion made about PEP technology stent. sten...

This article discusses the recent advances in polishing of advanced materials. Ninety-five journal articles published in 2005–2007 are briefly introduced. The topics are advances in chemical mechanical polishing (CMP), fluids for polishing, modeling of polishing, polishing of brittle materials, robotic polishing, polishing with vibrations or beams, and friction in polishing processes. CMP is pe...

Abstract Considering the increasing interest for Al alloys in packaging industry, where component lightweighting allows higher process efficiency, as well use of additively manufactured parts, which may not show a satisfactory tribological behaviour as-built condition, anodising by Electrochemical Oxidation (ECO) and Plasma Electrolytic (PEO) was applied to A357 (AlSi7Mg0.6) produced Laser Powd...

This paper discusses the surface modification processing of polished oxygen free copper using NaCl-electrolytic oxidizing water (hereinafter to as EO water). First, unheated test pieces were roughened by immersion with and without ultrasonic NaCl while comparing HCl solution. The after roughening treatment was observed FE-SEM measured AFM. results showed that has a stronger effect than solution...

This paper presents a polishing expert system integrated with sensor information which can modify the polishing sequence and conditions initially set by the system using the on-site polishing status. A practical system using AE sensors is developed for the rotational polishing and the curved surface polishing. A database and knowledge base for polishing processes are established by using the re...

The eddy current magnetic signature (EC-MS) method is a relatively new used to evaluate the residual stresses of ferromagnetic steels with higher sensitivity than other techniques. In this study, effects mechanical polishing and ferrite–pearlite structure on shape EC-MS signal were investigated in two experiments clarify effect compressive stress shape. first experiment, work-hardened layers sp...
