Magnesium and Magnesium Oxide Primer on AA2024-T351: Assessment of Field Performance

A Mg-rich primer (MgRP) consisting of metallic magnesium pigment was developed for the protection of AA2024-T351.1-10 Both a MgRP and a MgO-rich primer (MgORP) with topcoats were tested in laborato...

Development of a Predictive Corrosion Model Using Locality-Specific Corrosion Indices

Abstract : This Office of the Secretary of Defense Corrosion Prevention and Control Program project developed a statistical model of atmospheric corrosion of selected metals. This model relates measured corrosion rates at test sites (mainly military bases) worldwide to critical environmental variables. These variables are (1) a measure of atmospheric chlorides, (2) rainfall, and (3) relative humidity values at several levels. The measured corrosion rates obtained at test sites over the period of CY05 - CY07. Additionally this database includes much more data obtained from similar DoD monitoring activities over nearly the last decade. This serves to enhance the statistical relevance of the developed model. The model includes algorithms for several metals that have been routinely used in the monitoring work. These include copper, 6061 T6 aluminum, 7075 T6 aluminum, and a low carbon (1010) steel.

Scientific Investigation of the Corrosion Performance of Magnesium and Magnesium Oxide Primers on Al Alloy 2024-T351 in Field Exposures

The corrosion protection attributes of a magnesium oxide-rich primer (MgORP) on an AA2024-T351 substrate were evaluated after 2.5 y of coastal marine field exposure using several diagnostic electro...
