letter 7067
Stop corrosion of aluminum air
cylinder
+
I am working with an application that is forcing DI Water through
an aluminum air compressed cylinder that has a Nitrale o-ring. The
cylinder that is made of Aluminum will corrode within a day or two.
What can I do to stop this? Do you know where I could send my
cylinders to and have a coating applied that will be compatible with
Deionized Water, Diethylene Glycol, Dowanol PNP, Glycerin, Surfynol
465?

Electroless Nickel , Electroless Nickel Teflon, Anodize with
teflon seal are the coatings I would evaluate.I reccomend the teflon
because it makes the surface hydrophobic and DI water is very
corrosive.

U can find about plating in ASM
Surface Finishing Handbook.
