Abstract
The present invention relates to methods of enhancing the surface properties of soft alloys by using a high energy beam. In particular embodiments, the methods can also allow for beam-based welding of such soft alloys to another metal component.
Claims14
A method comprising:
- providing a component comprising a soft magnetic alloy with a crystal structure having long-range atomic order;
- and
- treating a surface portion of the component with a high energy beam, thereby melting and solidifying the surface portion to provide a treated surface portion, wherein the treated surface portion comprises a disordered surface layer having a grain size less than about 10 μm in size and a thickness of between 10 μm and 300 μm.
