Manganese phosphating is a process where a heavy deposit of manganese phosphate is applied to mainly steel and iron components either by immersion or spray. The colour of the deposit ranges from dark grey to black.
Phosphating is often carried out as a pre-treatment prior to other plating process but is also a stand alone process.
It may be specified for a number of applications including:
Components that require rapid break in or wear in.
To prevent galling without the coating flaking or peeling off.
To increase wear resistance.
To reduce wear during metal to metal contact
As a self-coloured corrosion resistant semi decorative finish (with oil)
