Parkerizing Receipe Solution
G'day Guys,
One of the proplems so far about living downunder is I can't source the factory made parkerizing solutions, well I can't find a retailer so far.
Does anyone have a good receipe for a homemade black parkerizing solution. A tried and tested one would be good. I have searched the net, come across a few receipe's but most links are dead to the poster so I can't ask any questions to try and convert the products to products sold here.
thanks,
Myles

:clap: You need a bath of : Phosphoric acid..........4.2g
Manganese dioxide.......2.5g
Distilled water...........1 litre
Cast iron fileings can be used instead of the manganese, boil for half to one and a half hours, must be kept boiling briskly. Allow to cool then rinse residue off, should be a slightly rough dark finish.
To parkerise use Phophoric acid......25.0g
Manganese dioxide..1.5g
Distilled water......1 litre
Boil in this mix for 2 to 4 hours, rinse in cold, then boiling water, allow a few seconds for water to evaporate then dip into Linseed oil, drain and dry.
These mixes are for small parts, increase proportionately for large items, and remember, do not let the mixture boil away to more than one third, otherwise........
