It is com-monly used in bearing and seals applications. Unfortunately, PTFE suffers from poor wear resistance. Gong et al. [6] and Blanchet and Kennedy [3] report unfilled wear-rates of 7.36 ×10−4 and 7.41 ×10−4 mm3/Nm, respectively. A hy-pothesis for the low friction of PTFE is that ...
Failure Mechanism of Polytetrafluoroethylene Under Friction …
WebOne material studied in the Tribology Laboratory is ultra-low-wear, low-friction hierarchical and multifunctional nanocomposites based on PTFE (Teflon®; lowest friction coefficient of any bulk polymer) that reduce its wear by more than 10,000 times with the inclusion of a few volume percent filler. Polytetrafluoroethylene is a unique and ... WebEarlier work has shown that the friction of polytetrafluoroethylene (PTFE) increases with increasing velocity and decreases with rise of temperature as though a relaxation process were involved.A study by microscopy, interference microscopy and electron microscopy of the friction tracks formed when PTFE slides on itself or on ‘clean’ glass shows that there … here for blood movie online
