PASSIVATION

Passivation refers to a process in which the surface of a material is treated or coated to prevent or reduce its susceptibility to chemical reactions, corrosion or other forms of degradation. The purpose of passivation is to create a protective layer on the material surface that helps the product to last longer.

The passivation process is of primary importance for the longevity of stainless steel, which removes less noble particles like iron, thus improving resistance and preventing surface corrosion, as it forms a protective layer that constitutes a physical barrier against external agents.

Passivation of stainless steel is a spontaneous process in nature but slow and uncontrolled, so at Posidonia we offer our customers the possibility to passivate anchors, chains, and deck elements quickly and in a controlled manner.
