Le, HR and Sutcliffe, MPF and Williams, JA (2004) Friction and material transfer in micro-scale sliding contact between aluminium alloy and steel. Proceedings of the ASME/STLE International Joint Tribology Conference, IJTC 2004. pp. 309-316.Full text not available from this repository.
A ball-on-flat reciprocating micro-tribometer has been used to measure the friction coefficient between aluminium alloy strip and a steel ball. A relatively small ball and correspondingly low contact load is used to give a contact width of the order of 100μm, closer to asperity contact widths than generally found for this type of test. The effects of load, initial strip surface roughness, lubricants and boundary additives are investigated. It is found that the friction coefficient is significantly reduced by the addition of a lubricant. Observations of the wear tracks and ball surface show that the material transfer from aluminium to the ball is reduced in the presence of the lubricant. The initial friction coefficient is further reduced by the addition of a boundary additive, but the friction coefficient after 8 cycles is unchanged.
