Subsequently, an alternative technique was developed by the Parker Company to utilize easier-to-obtain compounds at less expense through using zinc phosphating ( Parkerizing ) in place of manganese phosphating ( Parkerizing ).

Colquhoun of the Parker Rust-Proof Phosphating Company of America then filed another improved phosphating patent application in 1919 . This patent was issued in 1919 as, for an improved manganese phosphating ( Parkerizing ) technique.

From readings that I have done as well as speaking with applicators it seems one first uses an abrasive blasting procedure and then one can ALSO use a chemical treatment ( phosphating ) for added pretreatment before applying the powder.

Similarly, Baker and Dingman of the Parker Rust-Proof Company filed an improved manganese phosphating ( Parkerizing ) process patent in 1928 that reduced the processing time to of the original time that had been required through heating the solution to a temperature in the precisely controlled range of.

Parkerizing is usually considered to be an improved zinc or manganese phosphating process, and not to be an improved iron phosphating process, although some use the term " parkerizing " as a generic term for applying phosphating ( or phosphatizing ) coatings that does include the iron phosphating process.
