Zinc Plating Spec?
Zinc Plating Spec?
(OP)
Hi,
I would like to use a low or mild carbon steel for a part I am designing. The part is a cylinder. A low force (~2lbf) ball spring glides across the surface of the cylinder. I also need to prevent it from rusting. So, I would like to put a zinc coating on for corrosion resistance as well as strengthening the surface of the cylinder so the ball spring doesn't eventually wear grooves into it. On my print, how should I call out the zinc plating? Is there a standard that is typically used? What thickness is appropriate?
Thanks!

I'm also looking at using Al with a hard anodize, instead. Considering the load is only ~2lbf, any reason why the hard anodize might not work?
Would one be preferable over the other in terms of cost or effectiveness (effectiveness at wear resistance and corrosion, that is)?

Zinc plate, clear chromate @ thickness of .0002-.0004.
