 note = {application/pdf, In order to investigate the effects of cathodic protection on small corrosion fatigue crack growth behaviors, we conducted high-cycle reversed plane bending fatigue tests in sodium chloride solution using high-tensile-strength steel HT50 smooth plate specimens. The small corrosion fatigue crack growth rates under conditions of free corrosion potential and - 1.1 V (saturated calomel electrode SCE) showed a stress amplitude dependence at a constant stress intensity factor range, while those under the condition of - 0.8 V (SCE) did not show the stress amplitude dependence at a constant stress intensity factor range. The crack growth rates of small strface cracks were reduced remark-ably by the cathodic protection compared to those of the through thickness cracks. In the crack growth behaviors of the surface cracks, crack size dependence was observed in the effect of cathodic protection; that is, the degree of suppression of the crack growth rate by the cathodic protection became high with decreasing crack size., Article},
