Powercoating leaves of a spring?

When powdercoating the individual leaves of a spring stack, is there a risk of over-heating the springs and causing harm/weakness to them? What is the hottest temp you should heat the spring when coating? Or is this something to steer clear of?
Let's hear your opinions. Thanks.

 

Go ahead and powder coat them, the 400 degrees F or so will not effect the temper. I am curious about how long the epoxy will last with the leaf against leaf rubbing? Will it wear a pocket and bind up ?

 

I powder a bunch of em, and nope the temp doesn't affect them. I bake at 375

 

Does the coating stay on?

 

Yes, mine is powder coated and it doesn't crack off like you might think.

powder coating is basicly plastic and does have some flexibility. you could probably tailor the powder mix to be more flexible. it will wear at the contact points, but since it is bonded to the surface, it wont flake as much as paint. its safer for springs than chrome plating because there's no risk of hydrogen embrittlement.

 

I had the 6-leaf per side leaf springs of my 64 Galaxie coated several years ago and they still look great! I used a thin rubber strip in between the clamps though to prevent chipping.

 

Thanks for your posts.

 

400 degrees will not hurt your spring in the slightest and that is what powder coat should be cured at.

I think it would actually make for a smoother ride because powder coat is slippery.

 

I am using leaf liners on mine, but I went with an epoxy (KBS) coating on mine. (Just in case you are worried about the rubbing)

I used some plastic bags masking some stuff off. When the KBS dried I peeled it off of the plastic and it looks like a piece of powder coat that has peeled.

 

use the teflon ****ons at the rub points and you will be fine---can also be found in sheet and strip form

 

I even reversed the eyes on a powder coated main leaf and it did not hurt thew coating!!!

 

Anything under 500F is no problem for the spring.

 

Thanks again for all of the input. Wanted to hear from some with more building experience than me (which is just about everybody here.....HA!)
