Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates, to achieve corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. It is one of the most common types of conversion coating. The process is also called phosphate coating, phosphatization, phosphatizing, or phosphating. It is also known by the trade name Parkerizing, especially when a… WebMar 16, 2024 · Phosphating is a conversion coating that is applied to steel or iron components, and is mostly used as a pretreatment method in conjunction with another method of corrosion protection. The process involves immersing a component in a dilute solution, which then converts the surface of the metal into a layer of microscopic …
