Hi All,
Attached is a small selection of photos of some recently received parts for a product in development.
Not being too familiar with the field and having searched extensively for troubleshooting resources, I would now be very grateful for any input on some of the issues arising from inspection of the anodizing.
Material spec. depicted in each of the photos is 6082 T6; though we are having similar problems with 5251.
They are sulfuric acid anodized to Def Stan 03-25, and dyed black.
Please forgive my lack of technical terminology. Photo 012 shows areas almost absent of anodizing, particularly around corners. 019 shows a speckled finish on the fillet. 045 and 053 show similar.
Can anyone provide any insight into the cause of the problems and how they might be countered? I suspect the speckling is partly due to preparation of the components. The suspension of the components may also be a factor. I would like a reasonable understanding of the causes before approaching our supplier.
If any more information is required, please ask.
Thanks for you help!
