Innovative Nanostructured CerMets

For applications where tribological functionalities and enhanced mechanical properties of coatings are requested, innovative Nanostructured CerMets, are proposed.

A variety of WCCo powders able to avoid decarburization and innovative low density and environment friendly materials, were properly designed by MBN Nanomaterialia. Titanium and Iron-Chromium metal binders were chosen as base matrixes to substitute Cobalt and to reduce the weight of material employed to produce coatings. TiC and hard intermetallic reinforcements are proposed as WC alternative delivering high hardness and wear resistance.

To favor deposition of coatings by Cold Gas Spraying technology, powders in which chemical energy is partially stored within the material itself were developed. This leads to an “active” behavior of the materials, allowing to obtain materials showing exceptional performance after thermal treatment.
