Effect of Chloride Concentration on the Corrosion Rate of Maraging Steel
The corrosion behavior of
Maraging steel has been studied by using different techniques, including open
circuit potential and polarization measurements in addition to microstructure
examination such as optical microscopy and XRD (X-Ray Diffraction)
investigation. The corrosion behavior of Maraging steel has been examined in
sodium chloride solutions with different concentrations from 0.1 M to 2 M. It
was found that the corrosion resistance of Maraging steel is inversely proportional
with the concentration of sodium chloride solution. The corrosion resistance is
directly proportional to the Mo and Ti content in the Maraging steel. Heat
treatment of the Maraging steel improved its mechanical properties with no
effect on the corrosion behavior as the precipitation of inter-metallic
compounds leading to some galvanic action. However, sample IV having lower Mo
content than sample V showed after heat treatment an improvement in the
corrosion resistance.
