A gold marker technique revealing phase-specific wear and sub-surface deformation with nanometer resolution.

Abstract

Simple approaches such as increasing the macro-hardness of materials, no longer suffi ce, [ 2 ] as the ongoing miniaturization of devices and their increasing energy throughput, demand new concepts requiring an understanding of wear mechanisms at the nanoscale, [ 3–7 ] for which macro-hardness is not a reliable indicator. Currently, most experiments yield the amount of worn material as a function of the load and sliding distance. While such experiments will always remain important for the benchmarking of specifi c materials and lubricants, they can only yield an incomplete picture of wear mechanisms in the absence of microand nanoscale imaging. Early wear measurements involved weighing objects before and after rubbing, [ 1 ] but these methods require one to stop the experiment for data acquisition. By contrast, new methods involving chemical analysis [ 8–14 ]
