Anodizing Coefficient of Friction?
Q. Michael, if you're still out there, and magically still know, can you share the websites you found?

Q. Is the coefficient of friction (COF) of anodized aluminum less than the coefficient of friction of non-anodized aluminum? If so, by exactly how much?

A. Anodized Aluminum has a lower coefficient of friction than aluminum. I'm not sure myself by how much, but I'm looking for it.

Q. I am a student at the University of Wisconsin-Madison, and I am currently working on a design homework project for my statics course. In order to do this, I was wondering if anyone knew the coefficient of friction of anodized aluminum on anodized aluminum and the coefficient of friction of anodized aluminum on paper. I realize that there could be a broad range based on how the aluminum is anodized, but I would really appreciate a ballpark figure or some feedback of any kind.
Thank You for your time.

? Obviously Steve is doing the Statics design homework and is trying to find the lost and impossible friction coefficient for anodized aluminum. All I can say on this the biggest waste of time.... searching endlessly for a number I hopefully will never see again. And yes, Steve is right ... but do you really think, Steve, that someone who posted a question in 1999 is still sitting at his computer waiting for an answer?

Hi, Matt.
I read a "Hints from Heloise" in Good Housekeeping magazine once, wherein the inquirer asked Heloise what to do about having spilled red wine on her blouse. Heloise opened with: "If you can treat the stain before it dries..."
I think it's safe to say that Heloise did not honestly believe that the poor woman, many months later, was still in the restaurant, with a wet wine-stained blouse, waiting for the magazine to reach the news stand. Both Heloise's answer and Steve's will hopefully be helpful to the next person looking for it :-)

A. I found the coefficient on a couple of websites. They ranged from 0.2 to 0.7. Based on others that I have talked to, I have chosen 0.7 as the best possible choice.
