Abstract: The present work deals with the compressibility behaviour of a new generation of coated metal/ceramic composite powders. A commercial 316L stainless steel powder was coated with the alumina layer by an aqueous sol-gel colloidal process and then metal/ceramic composite materials were produced with core/shell structure. The powders were uniaxially cold pressed in a cylindrical die in the range from 200 to 1000 MPa. In order to reach the best green density, composite powders have been added with 1% in weight of l…
