| Summary: | Nano polishing is a method of using electrochemical polishing to achieve nano size structure of a metal surface. The study was focusing on electrochemical polishing of titanium alloy using ionic liquid. Ionic liquid was used in comparison to the conventional ways of using hazardous solvent. Three parameters were varied such as voltage, rotational speed and polishing time for the experiment. The experiment was also performed to study the surface roughness and grain formation after the electrochemical polishing of the titanium alloy. Based from the surface roughness tester and Scanning Electron Microscopy (SEM) images, the surface roughness of titanium is proven to be decreased with the use of electrochemical process. A sample surface roughness was reduced to 54.4% from the initial surface roughness. The best parameters to conduct electrochemical polishing were low voltage and high rotation speed. The use of Atomic Force Microscopy (AFM) was preferable to show the 3 dimensional surface representation. |
