metal oxides Switzerland

... conversion layers on magnesium that provide temporary corrosion protection. This protection can be significantly enhanced through subsequent sealing or coating. The patented technology of MAGPASS-COAT® utilizes oxidic products of the base material such as MgO, Mg(OH)2, as well as oxides from the passivation solution (MnO2, Mn2O3, and other metal oxides). Mechanical layer properties, comparable to chromate layers, are characterized by a layer adhesion of > 14.2 MPa. The layer thickness varies depending on the alloy, ranging from 0.3 to 1.0 µm, without compromising mass retention.
