Phosphate coating process
Did you know?
WebPhosphating also known as Parkerization, is a chemical phosphate conversion coating process whereby a microscopic layer of iron is removed and replaced with a comparably thin layer of either zinc or manganese dioxide to make the steel substrate more corrosion and wear resistant. The final result is an attractive and durable grey-black finish. 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 … See more The main types of phosphate coatings are manganese, iron, and zinc. • Manganese phosphate coatings are used both for corrosion resistance and lubricity and are applied only by immersion. • Iron phosphate coatings … See more Parkerizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a … See more Painting primer Phosphate coatings are also commonly used as an effective surface preparation for further coating and/or painting, providing excellent … See more • Henkel Surface Technologies—Current owner of Parco-Lubrite (a manganese phosphating process) and other Parkerizing rust-prevention coatings.
