Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1] [2] [3] It is one of the most common types of conversion coating.
A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound. These coatings are commonly applied to protect the part against corrosion , to improve the adherence of other coatings, for lubrication , or for aesthetic ...
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. Yaf 16:01, 5 December 2008 (UTC)
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.
Finally, the workpiece is re-immersed into the salt quench bath for 20 to 30 minutes, rinsed, and oil dipped. This last step optimizes the corrosion resistance by creating a layer of iron oxide about 3 to 4 micrometers thick. [5] It also gives the workpiece a black finish. [3] [6]
