Oxidizing Stainless Steel
Oxidizing Stainless Steel
(OP)
Hi, I was wondering if it were possible to effectively oxidize stainless steel for the purpose of blocking thermal radiation. (I had heard that oxidizing a material increases its surface emmissivity) Is this worth trying or a waste of time? Anybody have any other ideas about blocking high-temp thermal radiation?
Thanks for your help!

RE: Oxidizing Stainless Steel
What you do to the surface depends on what you want your heat sheild to do, and how much you can spend.
What is your temperature range?
(The surface of Stainless steel is already oxidized, its a thin transparent layer of CrO(n) (Funny I forget the valence) thats what makes it stainless.)

I love materials science!

The emissivity will change. I haven't run across any numbers, but using thoroughly oxidized SS tubes I almost double the outlet temperature of a solar heater I have in my greenhouse.

I would be interested in hearing about your solar heater. How it works and how the oxidized tubes made a difference.
