"Kinetic friction is primarily caused by chemical bonding between surfaces; however, in many cases roughness is dominant."
- mncharity 8y agoMy very fuzzy impression is HS friction is more roughness and debris than adhesion?[1] [1] "Bridging from Atomic Forces to Macroscopic Friction" http://online.kitp.ucsb.edu/online/suspensions-c18/robbins/ http://online.kitp.ucsb.edu/online/suspensions-c18/robbins/ . And the preceding "Contact of rough solids" http://online.kitp.ucsb.edu/online/suspensions18/robbins/ http://online.kitp.ucsb.edu/online/suspensions18/robbins/ . Robbins also has an old 2004 AJP article "Understanding and illustrating the atomic origins of friction" http://dx.doi.org/10.1119/1.1715107 http://dx.doi.org/10.1119/1.1715107 , but I've not skimmed it, nor explored its cited-bys for something similar but more recent.
