HSDM Development Observation of Corrosion in Brine

HSDM I - Low Corrosion rate

<1 mg/cm2/hr

HSDM II- High corrosion rate

<300 mg/cm2/hr

Corrosion in Brine occurs at the grain boundaries.

Corrosion in Acid occurs at the boundaries and the grain itself.

HSDM Development Corrosion Products

M(s) + H2O(L) M(OH)2(S) + H2(G) (in Brine)

M(s) + HCl(L) M(Cl)2(L) + H2(G) (in Acid)

Metal Hydroxide will precipitate

as a solid in brine.

Metal Chloride remains in

solution.
