How to verify that anodizing is completely stripped?




July 24, 2013

Q. Hellow,
I am trying to remove the anodized layer of aluminum part, and apply chemical conversion coating again.
And I must verify & prove that the anodic layer is completely removed.
But, the part is already in assembled condition.
So, I am going to remove the anodizing by manual sanding.

Therefore, we are looking for a portable inspection method.
Is there anybody who can help me?

A. Hi.
I normally check with a multi meter. Since an anodized coating is non conductive, a well stripped anodized piece would show conductivity.

Q. Thank you. SK Cheah.

Multi-meter can check on point to point locations.
But, I need to verify the entire stripped surface as requested by my customer.

Is there any detection solution for the above purpose ?

Thanks in advance !

Sorry! Finishing.com is temporarily Read-Only.
Ted Mooney is retiring but I have several offers to take it over.
We're working hard to make sure we find it the best new home.
