Abstract

Chemical surface modification can be used as a method for the corrosion protection of sensitive powders based on intermetallic alloys of RE-TM. The protection of the fine particles is based on the formation of a covalent bond between the particle’s surface and the surface-active substance. The monomolecular layer of organic substance does not detrimentally affect the magnetic properties of the powder and successfully protects the powder against humidity. Besides drastically improving the corrosion resistance of the powders the purpose of our work was also to improve their flowability, which is of great importance for industrial applications.
