MBN Nanomaterialia S.p.A.

MBN Nanomaterialia S.p.A. (Italy) was established in 1994 with core business being concentrated in the development of mechanochemical reactors for the production of nanophased materials produced by high energy ball milling.

Mechanical alloying is a solid-state powder processing technique involving repeated welding, fracturing, and rewelding of powder particles in a high-energy ball mill. Originally developed to produce oxide-dispersion strengthened (ODS) nickel- and iron-base superalloys for applications in the aerospace industry, MA has now been shown to be capable of synthesizing a variety of equilibrium and non-equilibrium alloy phases and nanocrystalline materials starting from blended elemental or prealloyed powders.

Nanocrystalline materials have been synthesized by a number of techniques starting from the vapor phase (e.g., inert gas condensation), liquid phase (e.g., electrodeposition, rapid solidification), and solid state (e.g., mechanical attrition). The advantage of using MA for the synthesis of nanocrystalline materials lies in its ability to produce bulk quantities of material in the solid state using simple equipment and at room temperature.

MBN have developed an unique oscillating high energy ball milling technology (HEBM) in which the grinding means are accelerated to the impact working surfaces at high velocities (several m/s) in an ordered and more controlled manner i.e. avoiding ball/ball collisions (EU patent deposited EP 0665 770). Using this method, the kinetic energy of grinding is purely transferred during impact from ball to powder (and partly to the container).

With an industrial production capacity of 100 ton/range, MBN’s mission is to bring nanotechnology from research environment to everyday life products offering to the market innovative nanomaterials adaptable to conventional and new powder metallurgy and deposition processes. The industrial production is focused on environmental friendly (Co free) nanostructured alloys for diamond grinding tools and high performance thermal spraying powders (Ti, WC-Co, MMC’s). All materials produced by MBN represent the direct outcome of scientific and technological research initiatives performed at National and European level in collaboration with Universities, Research Institutes and Industries. MBN is also working in the development of innovative material solutions in many application fields such as nanostructured metal and polymeric powders for high resolution additive manufacturing, polymer based alloys for textile and consumer goods and nanostructured Mg based alloys for hydrogen storage.
