Advantages of Phosphating in improving corrosion resistance Phosphate-coating

We consider ourself experts in phosphating treatment, thanks to our long experience we can offer/suggest numerous advantages to our customers. Phosphating is a temporary protective process that is also ideal as a pre-painting layer.

We have two types of processes available: phosphating by zinc salts (6-15 microns thick) and micro-phosphating by zinc-calcium salts (3-6 microns thick). Both treatments allow a superficial conversion of the substrates to a ferrous matrix, creating a protective layer composed of salts mixed with zinc phosphates.

One of the distinctive characteristics of phosphate-coating is its resistance to corrosion, which varies depending on the type of phosphating and the lubrications used, some formulated by important commercial groups, such as Quaker, Eni, Castrol and Fuchs oils. Furthermore, the resulting diamagnetic layer has a low coefficient of friction, which is further reduced when it comes by micro-phosphating. This layer offers effective protection against corrosion and a pleasant aesthetic, as well as advantages in terms of screwability for fasteners.

We have fully automatic phosphating systems, both with jigs (dimensions 1.00×0.50×0.50 m) and with rolling barrels. Each plant is equipped with a coating thickness measurement station and a control room that automatically manages the maintenance program and operating conditions.
