S1108-1-1 Creation surface by laser texturing

Abstract

This study is on removal of the work affected zone formed by laser texturing. For removal of the work affected zone some methods were tried, which of anodic-treatment, derusting agents and acid wash agents with buffing used commonly. Anodic-treatment could remove almost work affected zone and increase in the dimple volume. But pitting corrosion occurred with removal process at 2000 mV vs. SCE. In addition, friction test (vs. alumina ball) was carried out using specimens with buffing or anodic-treatment. There is a difference in frictional behavior due to the change in the dimple shape.
