Parkerising is an electroless metal protection process
suited to ferrous components that would benefit from
a self-lubricating, non-galling treatment.
The components to be parkerised are taken through
a 4 stage cleaning process and are then submerged
into the Parkerising solution for around 20 minutes.
During immersion, ferrous components react with the
solution until an insoluble ferro manganese phosphate
layer forms on the surface, preventing further reaction.
The parts are then rinsed and submerged into a soluable
oil solution that becomes dry to the touch.
Traditionally used in the finishing of gun barrels,
Parkerising is used to treat various components such
as those used in high voltage circuit breakers.
Parkerising is a low cost treatment but very effective.
