Hardcoat Anodizing of Die Cast Parts


I have this problem in obtaining good information concerning hardcoat anodizing of a die cast part. Enclosed is a photo of the results.

What is a good specification for hardcoat anodizing die cast parts? What is the process for anodizing? I would appreciate any assistance.

Unfortunately, sometimes, there is so much crap in cast parts, that there's nothing you can do with it. It appears you have quite a bit of junk in this particular casting you are working with.

Hardcoating die-castings is a very difficult process. The high level of alloying constituents interferes with proper coating formation. Highly conductive copper promotes "burning" while non-conductive silicon blocks coating growth. Most processes result in burnt parts or thin, smutty hardcoatings. Luke Engineering has developed a process, LUKON DC, to overcome some of these limitations. Hard, thick (up to 2mils) coatings are possible. However, even our best hardcoating on a die-casting is not as wear resistant as a typical hardcoat on a wrought alloy.
