Adhesion Failure on Aluminum
We powder coat aluminum bench seats in 6061 and 6063 alloy and structural steel parts on the same line. We have had trouble with periodic adhesion failure on the aluminum parts.
Q. We powder coat aluminum bench seats in 6061 and 6063 alloy and structural steel parts on the same line. We have had trouble with periodic adhesion failure on the aluminum parts. The parts pass an adhesion test in our shop but fail in the field. We use a five-stage cleaning process and an iron phosphate product with fluoride additive for the aluminum.
Is there a better product that will treat both metals in the same washer? How can we test the aluminum so we can see a problem before we ship it out? T.L.
