iron phosphating is the simplest method of phosphating. Easy
application and its working ability at lower temperatures make wipe
application iron phosphating very feasible. Metal parts are wiped,
brushed or cleaned with a sponge. It is preferred for such large
metal pieces which do not fit into phosphating baths (phosphate
coating tank) and also preferred when working area is not enough to
set up a continuous line or immersion line of phosphating.
coating by wiping is employed at between room temperature – 50 °C.
It is observed that working at higher temperatures is advantageous.
Concentration of the coating solution is between %8 – 10. With this
high concentration of chemicals, grease particles on the metal
surface dissolves by wiping with sponge or by a proper type of
It is recommended
to rebuild the working bath instead of adding phosphating chemicals
over used solution when active content of the solution is reduced.
