Ice vs. Teflon : coefficent of friction

[rollingstein]

I knew ice was slippery, but looking at a table of coefficents of friction today it seems that ice on ice yields a lower μs value than even teflon on teflon.

Is that really true? If so, does ice have much of an application as a lubricant or anti friction surface outside of skating rinks?

I was wondering...

Ice is slippery when enough pressure is applied, and you are moving; see

OTOH, teflon is always slippery!

Ice is slippery when lubricated with water. Pressure is one way to produce it, the other one is temperature.

Application areas: Skis, snowboards, skates, bobsled, luge, iceboats, avalanches, snowblowers, icebreaker hulls, river-bridge foundations, roofing, automotive exterior finishes, etc all concern interfaces to (and within) ice and snow. Traditional Inuit dogsleds use a smooth coating of ice on the runners to reduce drag over both ice and snow.

Yes, it is true that ice has a lower coefficient of friction than Teflon. This is due to the molecular structure of ice, which allows for a very smooth surface. However, this low coefficient of friction only applies to ice surfaces and does not necessarily translate to other surfaces. Therefore, ice does not have many practical applications as a lubricant or anti-friction surface outside of skating rinks. In fact, ice can often cause problems as a lubricant, as it can melt and refreeze, creating uneven surfaces and increasing friction. Teflon, on the other hand, has a wide range of applications as a lubricant and anti-friction material due to its low coefficient of friction and resistance to high temperatures.
