Tribo- and Tribocorrosion Properties of Magnesium AZ31 Alloy

In automotive and aerospace fields, the use of lightweight materials is required. Magnesium its alloys combine a low density with high mechanical properties excellent thermal conductivity. However, those suffer from corrosion wear resistances. The combined action also critical for these materials. Tribocorrosion magnesium alloy AZ31 has been investigated reciprocal sliding as function applied load in dry wet (NaCl) conditions. study shows that main mechanisms were adhesion, abrasion, oxidation while no adhesion was found wear. Corrosion worn surface occurs It interesting to notice less pronounced than due natural lubrication NaCl electrolyte. Only severe conditions, normal load, conditions bring filiform corrosion.
