Definition - What does Matrix Phase mean?
The matrix phase refers to a continuous phase in which a composite or two-phase alloy is formed in a microstructure of metals and completely surrounds the other (or dispersed) phase so as to ensure the stability of the dispersion phase. If done properly it can greatly increase the longevity of the material so as to prevent or stop corrosion altogether in metals.
Corrosionpedia explains Matrix Phase
The matrix phase keeps the dispersive phase in place while protecting the dispersive phase from the environment. Although the dispersive phase varies among different materials, the importance of the matrix phase is constant so as to ensure the proper execution of the dispersive phase. The successful execution of the matrix phase can greatly determine the strength of the bond in metals, which plays a role in how fast a metal corrodes.
