Abstract
Reactions between metal and environment can influence crack
initiation as well as crack growth under fatigue by several
mechanisms. Active corrosion allways accel-lerate the crack
initiation while the creation of stable passi-ve film under same
circumstances can delay fatigue crack initiation. Crack growth can
be accellerated by anodic dissolution, but very often the
accellerated effect is connected to hydrogen embrittlement due to
hydrogen uptake from a cathodic proces.Compared to crack growth
rate in air it is assumed that the increased rate seen for steel
in sea water under cathodic protection is due to hydrogen
embrittlement, while the increased rate found for steel in
district heating water can be explained by the combined action
from anodic dissolution and hydrogen uptake in the steel.
