Die castings pose some of the most challenging problems in
anodizing. The finish can be too thin, non-uniform and/or have an
unfavourable appearance.
These are common problems with a variety of practical solutions;
they are easy to recognize, but in many instances, the source for
the problem remains unknown.
Critical to solving the problems of anodizing die castings is
understanding the die cast substrate and the impact of surface
condition, alloy composition, casting quality and microstructure
on the anodizing process. Substrate quality issues are just as
important, maybe more so, than anodizing conditions and
technique. Certain optimum anodizing conditions may be used in
some cases to help overcome less than advantageous metallurgical
conditions. These include well known processing tools such as
various pretreatment chemistries, higher anodizing bath
concentration, and higher bath temperatures.These, and other
recommended solutions are not successful in every case;
sometimes trial and error testing on actual production parts must
be done to find the best processing techniques.
By providing real-life solutions in terms of anodizing theory and
interfacial science, this paper gives insight to anodizing solutions
for die-cast alloys by tying together metallurgical science with
anodizing practice. By Jude Runge* and Larry Chesterfield**
