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 .mu.m and 10 .mu.m, distributed uniformly in the matrix. The materials 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 nonoxidized 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 noncovalent bonds.
Composite materials resistant to wear and intended for covering pieces subjected to the phenomena of wear, erosion, cavitation and abrasion especially in a corrosive media, comprising a mixture of
Composite materials resistant to wear and intended for covering pieces subjected to the phenomena of wear, erosion, cavitation and abrasion especially in a corrosive media, consisting essentially of a mixture of:
