An Al-Cu-Fe alloy coating was deposited on the surface of diamond microcrystals via mechanical treatment of the powder mixtures in a planetary mill. The diamond crystals were 100 μm in size and had shapes close to truncated octahedron and cuboctahedron. The Al62.5Cu25Fe12.5 alloy was chosen as a model material to demonstrate the possibility of the coating formation from a brittle alloy on a hard substrate. The treatment was performed in steel vials with no balls added. During the treatment, fine particles of the alloy deposited selectively on the {1 1 1} facets of the diamond crystals. The material transfer from the alloy particles to the diamond facets was explained by considering the interaction of the particles with the wall of the vial.
