Three tribological regimes are identified depending on film thickness. In the first regime, an initial rapid decrease in friction is found when a film...

... 19 11 2008 It is shown that the main structural characteristic defining the wear value at friction is the shear-resistance of a polymeric matrix. The formation of the interfacial regions in the polymer composites results to the increase of this parameter. The mentioned criterion...
