Precipitation hardening is a heat treatment process applied to various alloys to significantly increase their yield strength.

Duplex stainless steels are considered magnetic due to their combination of austenitic and ferritic microstructure.

Dezincification is a problem unique to brasses i.e. alloys of copper and zinc.

There are a variety of approaches to limit the likelihood and impact of galvanic corrosion.

There are a number of different approaches to limit the likelihood or impact of galvanic corrosion occuring.

Galvanic corrosion is an electrochemical process that exists when two dissimilar metals are in contact with one another via an electrolyte.

As fretting corrosion will likely result in the removal of a significant proportion of the metal surface, the impact of it cannot be removed.

Fretting is the action of two metal surfaces rubbing against each other, resulting in mechanical damage.

The consequences of crevice corrosion are generally more severe than for pitting corrosion.

The impact of pitting corrosion will depend upon the extent and depth of the corrosion pits that are formed.

Pitting corrosion is a non-reversible process i.e. once corrosion has begun you can only deal with the consequences.

Pitting corrosion generally occurs in aggressive environments, and where the protective passive film is damaged.
