Another post with some links to resources I’ve found useful: this time, it’s sources for coefficient of friction data.
- General Magnaplate’s Friction Coefficient “Calculator” (actually just a lookup table): Mostly CoFs between General Magnaplate’s coatings and different materials, but also some between bare materials.
- RoyMech’s Coefficients of Friction page: A fair number of dissimilar materials comparisons, but also has elemental material and construction material CoFs.
- MechGuru’s Coefficients of Friction page: Lots of dissimilar materials CoFs – probably the most complete set here.
If there are any resources you like which I’ve missed, let me know!
(Note: Again, I’m not affiliated with any of these groups, and have no responsibility for/ownership over the content of these pages – I just think they’re useful! Additionally, be aware that a) the data from these sources is unverified – at least by me – and b) friction coefficients are challenging to determine conclusively regardless. They can vary widely based on geometry, surface finish, other surface conditions: you should always verify coefficients experimentally in critical applications.)
