MAY THIS HELP YOU MY FRND!!!
The friction force depends on two factors:
a) The materials that are in contact. The two materials and the nature of their surfaces. Rougher surfaces have higher coefficient of frictions but to slide apart.

1) Roughness of surface : More the roughness of surface, lesser the friction.
2) Surface in contact : If two smooth surfaces are in contact, the force of friction when acts between them will be higher.
[NOTE : THE FORCE OF FRICTION DOES NOT DEPEND ON THE MATERIAL OF THE BODY]
