Lubrication Film Wear and Tire Wear
These particles are from a blower housing in a automobile
parking facility. The gray elongated cylander in the center
of the field is the lube wear. The black tapered cylanders on either side and at the
edges of the image are tire wear. This lube wear particle
would be considered black if it were not with the darker tire wear.

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.
