E-pH Diagram of Metals. Building a Pourbaix or E-pH diagram to represent the stability of a metal or an alloy in a given environment is not an insurmountable task. However it could take a few hours of your precious time to produce what is commonly a universally accepted tool to discuss the expected behavior of metals, many Thanks to the well known Belgium scientist that gave his name to these.

[en] Research highlights: → The titanium solubility range increases slightly with increasing Br - activity. → The passivation area decreases slightly with increasing Br - activity. → Immunity area increases slightly with increasing Br - activity. → The titanium immunity disappears in the presence of titanium hydrides.

The diagrams were compared with the simple Ti-H 2O system at 25 oC. Comparison of the simple Ti-H 2O system with the diagrams of the Ti-Br --H 2O system at 25 oC showed that the titanium solubility range in the acid, neutral, and weak alkaline areas of the diagrams extended slightly to both higher pH values and potentials with increasing bromide ion activity and decreasing water activity.
