composites

Arming of metal alloys by high strength refractory particles is one of the most common methods for wear resistant, tribological or mechanical properties improving, such materials is called – metal matrix composites. Nanoparticles via mutual contact tend to be agglomerated; they become stable only at micro sizes. Thermo-chemical and mechanical fixation of nanoparticles on the surface of metal powder particles forms micro-nano granules. Such combined micro-nano objects have numerous advantages that allow consolidating them in bulk composite material by extrusion or impregnation methods.
