Abstract Scope |
Among the various advantages of Porous metals (PMs), the large surface area is one of the most important key characteristics, accelerating chemical reactions on the surface. That is why the PMs can be actively used for electrode, catalyst, or biomedical applications. Since the surface morphology, as well as the area, also has an important role, it is necessary to investigate the morphology of the ligament surface.
In this study, we fabricated porous Ti by the LMD process and studied the etching-rate effect on the surface morphology change. As a melt material for the process, Ca alloy melt was utilized since Ca react actively even with pure water. By changing the etching rate, the surface morphology was changed from smooth (nitric acid) to hexagonal-facted (water). Through this work, we can suggest a way to control the surface morphology by changing the etching rate, providing new applications for metallic foams. |
