CEBALLOS, WILSON FERNANDO; GOMEZ, ADOLFO LEÓN e CORONADO, JOHN JAIRO. THE SYNERGISM BETWEEN HIGH SUPERFICIAL ROUGHNESS AND CORROSIVE ATMOSPHERE IN THE FATIGUE BEHAVIOR OF THE SAE 1045 STEEL. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.154, pp.91-100. ISSN 0012-7353.
The fatigue behavior of the SAE 1045 steel in four different conditions is reported in this paper. Four treatments were tested: polished surface, corrosive atmosphere (sugar cane juice), low quality roughness (typical equivalent surface of the shaft cane mill) and the combined condition of the two last treatments involved. Fatigue tests were performed in rotating bending conditions and the values of fatigue strength for the different situations from tests were obtained. The diminution in fatigue strength for the synergy condition of rough surface and corrosive atmosphere was of 8.7%, result statistically representative with less than 0.01% of uncertainty.
