Abstract
This paper aims to present to the analysis about the resistance to wear by dry a steel x steel pair when normal force variation occurs . The method used to perform the sliding wear tests was the pin-on-disk test, keeping the pin and disk hardness constant (340 and 380 HV, respectively), with 05 tests for each pin-to-disk pair, as a function of 02 (two) normal load values (35 N and 70 N). To perform the tests were used ABNT 4140 steel pins with 5 mm diameter for 15 mm in length and ABNT H13 steel discs measuring 76 mm in diameter by 4 mm in thickness. The study showed that with the increase of normal force the analyzed factors also presented growth, the pins, mainly, with the applied load of 70 N suffered a very high increase reaching a difference of 120% in the level of hardening when compared with the material before the test.
