A known problem of additive manufactured parts is their poor surface quality, which influences product performance. There are different treatments to improve quality: blasting commonly employed mechanical properties and reduce roughness, electropolishing clean shot peened surfaces the roughness. However, final roughness conditioned by multiple parameters related these techniques. This paper pre...

Although copper is widely used as an electrocatalyst for the CO 2 reduction reaction, often little emphasis placed on identifying exactly facet distribution of surface. Furthermore, because differing surface preparation methodologies, reported characaterization voltammograms (where applicable) vary significantly between laboratories, even surfaces supposedly same orientation. In this work, we d...

This work investigated the ability of electropolished Ti surface to induce Hydroxyapatite (HA) nucleation and growth in vitro via a biomimetic method in Simulated Body Fluid (SBF). The HA induction ability of Ti surface upon electropolishing was compared to that of Ti substrates modified with common chemical methods including alkali, acidic and hydrogen peroxide treatments. Our results revealed...

Microstructural characterization of plutonium by electron backscattered diffraction (EBSD) has been previously elusive primarily because of the extreme toxicity and surface oxidation rates associated with plutonium metal. In this work, initial electron backscattered diffraction pattern (EBSP) observations of a plutonium-gallium (Pu-Ga) alloy were made. Samples were prepared using standard metal...

The enormous demands for metal implant have given rise to a search for cheap material with good bio-tolerability and resistance to corrosion. Although stainless steel has these properties and is widely used for this purpose, its long term application is still a concern. The corrosion resistance of stainless steel depends on the passive layer. Herein, chemical surface treatment, including passiv...
