Summary

Magnesium is an abundant metal in nature but it presents a low mechanical strength and plasticity due to its hexagonal crystal structure what forces us to use it in hardened and alloyed structural applications by heat treatment. In these conditions we achieve a suitable link between strength and weight and, except for chlorides, a proper fatigue behavior.

The other major limitation of magnesium and its alloys is their low strength to corrosion because of high electroactivity. However, these materials present an advantage: their remarkable low densities (1,7gr/cm3), which are close to polymeric materials (79% lower than steel and 37% lower than aluminum that is the most common of slight alloys). These circumstances have recently awakened a high interest of researchers to correct, when possible, their limitations with reliability in order to use them for structural applications.

During the seminar, the speaker will describe the achievements using surface engineering to improve corrosion and wear behaviors of these materials by nuclear fusion with laser in order to achieve beneficial surface microstructural changes.
