Development of Microtextured Mold and Its Application (3rd Report)

- Complicating Texture Patterns by Microcutting Using Indenter Edge -

Abstract

Improving materials surface functions using micro-textures is of great interest in various fields. The authors have also performed to improve the photocatalytic surface functions by introducing the microcutting textures and achieved an improvement in the hydrophilicity, which is one of the photocatalytic functions, due to the increase in the real surface area. In this report, vibration assisted microcutting was conducted on a pure aluminum workpiece using an edge of the diamond indenter as the tool rake and a depth of cut of less than zero in order to fabricate finer and more complicated micro-texture. As a result, finer and more complicated microcuttting surface texture composed of numerous plastically deformed micro embossments, impressions and flat portions was successfully fabricated on the workpiece.
