Galvanic corrosion properties of differently PVD-treated magnesium die cast alloy AZ91

The publication shows the results of a novel immersion technique to determine the time dependent corrosion behaviour of coated magnesium alloys [B.L. Tiwari, J.J. Bommarito, Magnesium Technology 2 (2002) 269.]. Furthermore, the galvanic corrosion properties of differently coated AZ91 samples in contact with untreated AZ91, different aluminium alloys, roller bearing steel 100Cr6 and a titanium alloy TiAl6V4 were determined. The galvanic corrosion properties were tested according to DIN 50019.
