Hi all,
I recently bumped into an issue below:
A part meant for aerospace usage was yellow chromated as per AIPS02-05-001, The Airbus Process Specification for Chemical Conversion Coating. The base material is A2024 CLAD T351.
Upon inspection of the processes part, we notice a symptom of 2-tone colour of the final finishing.
Eventually, the appearance of the machined area of light-bright-yellowish was the desired result. However, the original CLAD surface (non-machined area) appears as dull-brownish colour.
The issue now: IS THIS NORMAL? I personally had seen quite a number of yellow chromated aluminium parts, but this is the first for me...
Appreciate if anyone could share your comment and experiences..
P.S.: I was not able to post a link as I had too less post. If you would like to see the photo of the actual part, please let me know and I would PM you..
