It's called 'fretting'.

Fretting refers to wear and sometimes corrosion damage at the asperities of contact surfaces.

This damage is induced under load and in the presence of repeated relative surface motion, as induced for example by vibration.

It's a particular wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other force.

The amplitude of the relative sliding motion can be as low as 3 to 4 nanometers, extremely small!

The contact movement causes mechanical wear and material transfer at the surface, often followed by oxidation of the debris and the freshly-exposed surface. The oxidized debris often act as an abrasive since it is usually much harder than the underlying metal surfaces and is like having carborundum dust between the surfaces.

I did SAY that those three 6mm bolts were not man enough to contain that lump!.

Will the clutch start to wear and come loose?

Probably, unless you constantly check and clean behind it.

Thats why you get the rusty dust under the pins on the old clutches as they start to loosen.
