Friction behavior of DC54 hot-dipped galvanized steel strips under the condition of friction coupling with deformation

Frictional wear behavior under the condition of friction coupling with deformation between a DC54 hot-dipped galvanized steel strip and a sliding block made of quench tempering DC53 cold-work die steel was studied on a self-made tester of friction coupling with deformation.Stress distributions along the thickness direction and the rubbing surface of the DC54 hot-dipped galvanized steel strip were calculated by a finite element method.The results showed plastic deformation was the key effect factor of frictional wear behavior under this test condition.With increasing load,friction between the strip and the sliding block increased and the wear got severer.
