A pourbaix diagram is a plot of the equilibrium potential of electrochemical reactions against ph. It shows how corrosion mechanisms can be examined as a function of factors such as ph temperature and the concentrations of reacting species. E ph diagram of metals.

Solid line a cl l dashed line a cl 2.
An equilibrium potential ph pourbaix diagram is presented for sulfur adsorbed on ag 1 1 1. Eh ph diagrams are thus essential to understanding solute and radionuclide transport in groundwater. The former discussed corrosion passivation and immunity of materials while the.
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. Pourbaix diagrams 43 4 1 basis of pourbaix diagrams 43 4 2 pourbaix diagram for water 44 4 3 pourbaix diagram for iron 45 4 4 pourbaix. Theoretical conditions for the electroless plating of a metal may be determined from the pourbaix 1 diagrams for the metal and the principal element in the reducing agent.
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. A summary of common reducing agents that may be employed for electroless copper plating is given in table 12 2. The most well known studies on comprehensive eh ph diagrams are those of pourbaix 1966 and brookins 1988.
