In this work, the Yb:YAG laser beam welding of the magnesium alloy AM60 was studied. A laser power of 2 kW and a welding speed of 3.5 m / min give a different welding quality than that obtained by CO2 laser with the same parameters. The metallurgical

Ceramic Coatings on Titanium Alloy by CO2Laser Treatment

Autor: Jean-Francois Mathieu, Jean-Eric Masse

Publikováno v: Materials and Manufacturing Processes. 11:199-206

Titanium alloys are widely used in various industrial sectors, especially in aeronautics, due to these specific properties: low density, good corrosion resistance, and fairly good mechanical properties. However, they have low wear and gall resistance
