Definitions
Corrosion fatigue testing

Fatigue-corrosion tests use fatigue terms, specified at [63], and corrosion terms, specified at [64]. Some definitions, however, are typical of fatigue-corrosion tests (ASTM standard E 742, see [Doc. M 135]).

Fatigue-corrosion: the combined effect of fatigue and an aggressive environment acting simultaneously, leading to a deterioration in fatigue behavior.

Deaeration: the process of removing gases from a liquid environment before and during fatigue testing.

Environment: the set of chemical elements and energy surrounding the test sample.

Corrosion cell: container holding the useful part of the test specimen.

Corrosive medium composition: concentration of chemicals in the liquid medium during fatigue-corrosion tests.

Hydrogen or oxygen content: concentration...
