Remelting Alloying

By means of the electron beam the boundary layer of a material is melted to a maximum depth of 10 mm. The base material is fused with a filler material that has previously been applied on the work piece or is added during the process. As a result, an alloy of a new composition is produced in the boundary layer.

In the case of thin boundary layers, rapid solidification does not leave enough time for precipitation to take place, resulting in “oversaturated solid solutions” which offer improved hardness and wear-resistance characteristics. Hardness values of more than 300 Vickers are usually achieved using alloying at Aluminium cast alloys.
