Performance Anodic Coatings

Spalling Free Dyed Anodize

What We Do

Spalling Free Dyed Anodize (approved for Lockheed specification where spalling is a requirement)

Spalling (separation) of the anodize coating from the aluminum substrate is catastrophic failure of the coating due to a combination of alloying metals collecting at grain boundaries (typically zinc in 7075 aloy), dying and incorrect anodizing procedures. Hillock Anodizing is a Lockheed Approved vendor and approved for MAP-311085. MAP-311085 occasionally requires spalling testing be performed with a lot of parts. Our standard process dyed black successfully passed the spalling test on 7075 aluminum.
