Abstract

An atomic force microscopy study is presented on lubricating systems, such as thin organic Langmuir-Blodgett films. Local elastic compliance was measured simultaneously with topography and friction on thin films of mixtures of fluorocarbons and hydrocarbons. On the phase-separated fluorocarbon domains, higher friction and lower Young`s modulus than on the hydrocarbon domains was found. Adhesive wear has been observed to occur randomly on the stiffer hydrocarbon domains if the film is complexed with a counterion polymer of a larger cross-sectional area. A quantitative fractal analysis of the hydrocarbon film remaining areas provided a linear adhesive wear dependence on the scan cycle number.
