    摘要: The invention relates to a lubricating metal coating and to a process for its preparation. The material constituting the coating in a composite material comprising a metal matrix within which talc particles are distributed as lamellae, the metal matrix being composed of a metal chosen from Fe, Co, Ni, Mn, Cr, Cu, W, Mo, Zn, Au, Ag, Pb or Sn or of an alloy of these metals or of a metal/semimetal alloy. The coating is obtained by a process consisting in carrying out an electrolytic deposition using a solution of precursors of the metal matrix of the coating which additionally comprises talc particles in suspension, which particles are modified at the surface by irreversible adsorption of a cellulose-derived compound by replacement of all or part of the hydroxyl groups.

    摘要: A method for preparing a composition including mineral particles, that is swelling TOT-TOT interlayer particles, formed by interlayering between: at least one non-swelling mineral phase formed by a stack of elementary laminae of the phyllogermanosilicate 2/1 type and of formula —(SixGe1−x) 4M3O10(OH)2—, and at least one swelling mineral phase formed by a stack of elementary laminae of the phyllogermanosilicate 2/1 type and at least one interlaminar space between two consecutive elementary laminae, the swelling mineral phase being of formula —(SixGe1−x)4M3−εO10(OH)2, (M2+)ε′.nH2O. The composition is prepared by subjecting a gel containing silicon, germanium and metal, of chemical formula —(SixGe1−x)4M3O11,nH2O—, in the liquid state to a hydrothermal treatment which is carried out over a defined period of time and at a temperature of between 150° C. and 300° C., the time and temperature being selected according to the desired structural characteristics for the swelling TOT-TOT interlayer particles to be prepared.
