Proc. ASME. IJTC2011, ASME/STLE 2011 Joint Tribology Conference, 1-3, October 24–26, 2011
Paper No: IJTC2011-61008
... 10 02 2012 Low friction polytetrafluoroethylene (PTFE) has been studied extensively and is widely used in tribological applications in bulk form. Tribological properties of thin film PTFE are less reported due to its poor wear resistance. Here, we show that by incorporating Au...

Proc. ASME. IJTC2010, STLE/ASME 2010 International Joint Tribology Conference, 77-79, October 17–20, 2010
Paper No: IJTC2010-41027
.... The wear caused on the bearing surface is modeled using Dufrane’s abrasive wear model. The Reynolds equation based on Constantinescu turbulent lubrication theory has been solved using FEM and Newton Raphson method along with the appropriate boundary conditions. The numerically simulated results have been...

Proc. ASME. IJTC2007, ASME/STLE 2007 International Joint Tribology Conference, Parts A and B, 11-13, October 22–24, 2007
Paper No: IJTC2007-44131
... 26 03 2009 The friction and wear properties of nanocrystalline cobalt (nc Co) with a grain size of 20±5 nm and a hardness of 503±13 HV were studied using a pin-on-disc tribometer. Tests performed under unlubricated sliding conditions in ambient air showed that large tribolayer area...

Paper No: TRIB2004-64136
..., dissolution of alloying constituents from the bronze bearing material dissolute into the synthetic ester lubricant occur leading to the formation of a copper enriched bearing surface layer. Tin-bronze with synthetic ester lubricant showed more stable friction values and roughly ten times better wear results...

.... The shims with parallel line V-grooves showed the highest friction reduction (up to 35%) compared to production shims. There appears to be no significant difference in wear pattern on cam lobes tested against production shims and shims with parallel line V-grooves. Also, the wear rate of a shim...

.... This was attributed to the decrement of the shear stresses at the surface between the shaft and the fluid. It is also shown that the amplitude of the vibration signal when analyzed through wavelet theory is lower for the case with coating compared with the no coating. Triboadhesion bearings wear surface...
