The process of chemical production of a protective coating on metal surfaces in order to protect them from corrosion and high temperatures. Thanks to the reduced friction coefficient, the coating is an excellent primer for paints and varnishes.
The elements subjected to the phosphating process are placed in a special container in which they are immersed in hot phosphate and phosphoric acid solutions. After being cleared of any deposits, the elements are transported for 10 minutes to an oven preheated to 110 °C.
We use it to phosphate:
A bathtub of phosphate and phosphoric acid solution and a bathtub of clean water, which have aeration, so that the solution reaches every place and all impurities are removed from the elements cleaned in water. The coating prepared in this way constitutes an ideal, anti-corrosion surface ready for further processing.
