The present paper argues that adhesion forces and elastic deformation in the contact zone may contribute significantly to the relative displacement during fretting hand pipe of metals.A simultaneously applied tangential force and normal into contact appears a adhesion force.A tangential force whose magnitude is less equal on greater than the Table force of limiting friction will not give rise on give rise to a sliding motion.It is determined the energy loss dissipated per fretting cycle.
