What happens when PTFE and Hastelloy C rub against each other?

Answer 1

PTFE (Teflon) rubbing on PTFE will create a bit of friction, depending on the load. And it will create heat. Remember that PTFE is pretty "slippery" and will not abrade too quickly unless a gross amount of force is applied.

Answer 2

Friction. PTFE is a polytetrafluoroethylene - Teflon®. It's slippery. Slick. Hastelloy® C is just a specific alloy of nickel steel. But which one? (There are dozens.) Not that it matters that much. It almost seems as if the question was made "difficult" or "obscure" for some reason. Teflon is an amazing substance. It is resistant to attack by most chemicals. This largely inert material is also used in finely divided form as a lubricant additive. It's got great "slipperyness" to it. Rubbing steel on it will create friction and heat, but that and wear will be minimal compared to most of other things the steel could be rubbing on. The heavier the load, the more trouble the Teflon will have supporting it. It is, after all, a polymer, and it isn't super hard, so it can suffer "crush" damage when highly compressed.

Answer 3

When PTFE and Hastelloy C rub against each other, there is minimal wear and friction due to the low coefficient of friction of PTFE. This leads to reduced wear and damage on the surfaces in contact. However, some transfer of material from one surface to the other may occur, potentially affecting the performance of the components.
