Tribological and Rheological Properties of Thermally Treated Steel under Reverse Friction

Resumo

Changing the sclerometric parameters and acoustic emission activity of friction zones depending on the tempering temperature of carbon steel quenching under conditions of cyclic-reverse scratch-testing is studied. The tribological analog of the Baushinger effect, whose occurrence depends on the structure of steel tempering, is experimentally researched. The physical nature of Baushinger’s triboeffect as a rheological parameter of relaxation and the dissipative properties of the frictional contact are examined in connection with the acoustic emission activity and amplitude dependent internal friction of steel.
