The force of friction between their surfaces touching each other.

Friction, if that is what you mean.
When two surfaces rub against each other, friction is formed. It is the force resisting the relative motion between fluid layers, solid surfaces and material elements that are sliding against each other.
Not necessarily.

Metals often wear each other away as a result of friction between adjoining surfaces.
A very, very tiny fraction of the two surfaces are eroded.
yes it does it can be stronger and weaker depending on which two surfaces rub against each other
The friction that two surfaces excert on each other when they rub against each other is called a friction.
