Abstract:
A streak defect on anodized aluminum is a major problem in the aluminum extrusion
industry. It causes uneven color (dull or bright) on the surface of the extruded parts and can
be easily observed. Many factors can contribute to the streak defect, such as poor surface
quality of the extrusion die, abrupt change of bearing on the extrusion die, etc. In the current
practice, a trial and error method is used during the etching process to eliminate the streak
defect and this approach increases the production cost and time. The aim of this study is to
experimentally investigate the effect of etching process parameters, i.e., etching time, etching
temperature and concentration of NaOH etchant, on final roughness of etched aluminum parts
and amount of material loss. Based on these results, guidelines for suitable etching process
parameters to eliminate the streak defect on aluminum extrusion parts are provided
