Definition/Function:
These particles are an example of lubrication film wear. These include roller bearings,
drive belt wheels,
file cabinet drawers, desk drawers, and even overhead cranes. They are formed by the
slight slippage that occurs during motion and
the hydrocarbon film that develops on the metal runner over time. These particles are
typically black, with an organic matrix and
significant numbers of very small metal wear particles.
