Surface Preparation Evaluation: Useful Anodizing Check Methods

Summary for surface preparation evaluation Discussion

Surface preparation evaluation for anodizing is the focus of this thread: Bastian Azmold asks for ways to check rinsing, degreasing, and activation on aluminum before anodizing, specifically looking for alternatives to SEM/EDS and citing copper sulfate testing used in steel plating. The excerpt provided contains only the question and no posted answers, so no specific method is recommended in the source text. The practical takeaway is that the thread is seeking a way to verify cleanliness and surface condition before anodizing, but this excerpt does not document a consensus or named expert advice. Readers would need the full discussion or additional sources to see whether wet tests, contact-angle checks, break-free water tests, or other inspection methods were suggested.
