Corrosion Protection
____________________
A. Surface Treatments (Galvanic or Chemical)
(1)
The surface treatment for aluminum-alloy components are yellow chromating or chromic acid anodizing.
(2)
Aluminum-alloy components that are bonded have a surface treatment of chromic acid anodizing or pickling and bonding primer.
(3)
Steel parts have a surface treatment of cadmium plating, chrome plating or phosphating.
(4)
Titanium or stainless-steel components that are assembled to aluminum alloy components have a surface treatment of cadmium, zinc, or aluminum plating.
(5)
A paint surface treatment has a polyurethane or epoxy primer to give protection against corrosion. A polyurethane topcoat is applied to give protection against a chemical attack.
B. Protection of Mating Surfaces
(1)
In addition to the surface treatments already applied, a sealant or anticorrosion material is applied between components assembled together.
(2)
A chemical conversion coating is applied to rivets installed in light alloy, anodized titanium and cadmium-plated steel components.
(3)
Shafts are assembled installed and coated with grease or
anticorrosion materials.
(4)
An application of paint or soft varnish, after components are assembled protects the joint seams.
(5)
Sealant is applied to protect bonded edges, in areas exposed to corrosion attack.
