It is also known by the trade name Parkerizing, especially when applied to firearms and other military equipment. [5]: 393 A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts.
A common example is phosphoric acid, which additionally converts some iron oxide into an inert layer of ferric phosphate. [3] Most of the rust converters contain special additives. [4] They support the rust transformation and improve the wetting of the surface. Applied rust converter
Once cool, oil is added, to fill the pores in the phosphate coating on the surface, thereby increasing the resistance to rusting, for items that are not going to be painted. Alternatively, paint can also be applied over the phosphate coating to fill the pores, in which case, no oil is used.
A pigment with anticorrosive properties is zinc phosphate, which now replaces the similar red lead. Compounds derived from tannic acid or zinc salts of organonitrogens (e.g. Alcophor 827) can be used together with anticorrosive pigments. Other corrosion inhibitors are Anticor 70, Albaex, Ferrophos, and Molywhite MZAP. Oil field industry.
The choice of additives is determined by the use, e.g. the oil for a diesel engine with direct injection in a pickup truck (API Service CJ-4) has different additives than the oil used in a small gasoline-powered outboard motor on a boat (2-cycle engine oil).

Trisodium phosphate (TSP) is an inorganic compound with the chemical formula Na 3 P O 4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent , builder , lubricant , food additive , stain remover , and degreaser .
Oligonucleotide phosphorothioates (OPS) are modified oligonucleotides where one of the oxygen atoms in the phosphate moiety is replaced by sulfur. They are the basis of antisense therapy, e.g., the drugs fomivirsen (Vitravene), oblimersen, alicaforsen, and mipomersen (Kynamro). [3]
