A new tool for industrial tribology filling the gap between macro‐ and nano‐ tribology

The aim of this paper is to illustrate the similarities and variations between friction and wear data acquired with two different types of laboratory tribological test equipment that not only operate in the gap between macro- and nano-testing, but also provide test parameters that allow an overlap across the whole scale from macro- to nanoscale friction and wear tests. Comparative wear tests were conducted under identical test conditions in the overlap region between macro- and micro-regions using an existing piece of laboratory fretting test equipment and a novel one. The experimental test data obtained with these two experimental set-ups are discussed.
