ABSTRACT OF THE DISCLOSURE The subject composite materials comprise an association of an organic elastic matrix with a network of non-oxidized quasi spherical particles, of submicronic dimension and of a diameter ranging between 0.1 µm and 10 µm, distributed uniformly in said matrix. They are intended to coat pieces subjected to the phenomena of wear, erosion, cavitation and abrasion notably in a corrosive medium. According to a method of manufacture of these composite materials, the non- oxidized submicronic particles are, immediately before their introduction in the organic matrix, plunged into an organic macromolecular dispersant chosen of such type that the macromolecular chains of the dispersant are fixed on the surface of the particles by non- covalent bonds.
