In this case they use superdupercomputer modeling to understand what's happening at the pressures experienced at the point of contact.
In order to come up with a theoretical understanding of exactly what the tribology team was seeing during their testing, they worked with Sankaranarayanan and Narayanan who had previously used the immense computing power of ALCF’s 10-petaflop supercomputer known as Mira. They ran large-scale simulations in order to get a better understanding as to what was happening on an atomic level and realized that the catalyst metals in the nanocomposite coatings were stripping hydrogen atoms from the hydrocarbon chains of the lubricating oil. They were then breaking down the chains into even smaller segments. These smaller chains came together under pressure and created the highly durable DLC tribofilm.

Sankaranarayanan says this is an example of catalysis under extreme conditions created by friction. It is opening up a new field where you are merging catalysis and tribology, which has never been done before. This new field of tribocatalysis has potential to change the way we look at lubrication.
Any sufficiently advanced technology is indistinguishable from alchemy.
