    摘要: 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.

The mixture is of a composition within the portion of the phase diagram of the mixture corresponding to a single homogeneous liquid phase in the region of temperatures above the melting point of the alloy to be treated. The treating composition is used in the form of a homogeneous liquid or a substantially homogeneous solid which melts at contact with the alloy.

    摘要: The method causes the deposition of calcium or calcium alloy to a cathode by electrolysis of a calcium derivative in a bath of molten salts based on calcium halides. The calcium derivative is in solution into the molten salt bath in ionic form. For producing calcium alloy, calcium is caused to deposit on a liquid metal cathode and the calcium is alloyed in situ with the metal of the cathode to form the alloy. The method enables the production at the anode of high purity metals such as graphite carbon or silicon from calcium carbide, respectively calcium silide or calcium silicon. It is also possible to obtain high purity calcium by decomposition of the alloy obtained by vacuum distillation.

    摘要: Metal in the form of granules is solidified from the molten state by forming a jet of molten metal which is caused to pass through a vibrating orifice in order to divide the jet into individual drops and causing solidification of the drops by cooling so as to form the granules. The drops of the jet are caused to fall from the vibrating orifice under the action of gravity through an inert gas atmosphere which is maintained at a temperature below the solidification temperature of the molten metal. In the case of reactive metals, the jet is formed by withdrawal from a mass of molten metal maintained in contact with a bath which is not miscible with the molten mass and selectively dissolves the derivatives produced in the event of oxidation.

    摘要: A metal halide is reduced by reacting it with calcium carbide in a bath in which the calcium carbide is dissolved in a mixture of a halide of at least one alkali metal, specifically sodium, potassium, rubidium and/or cesium, with a halide of at least one alkaline-earth metal, specifically calcium, strontium and/or barium. The desired metal may be one of the aforementioned alkali or alkaline-earth metals, e.g. sodium or magnesium, in which case its halide is one of the constituents of the mixture. Otherwise, a vapor of a halide of the desired metal (e.g. titanium tetrachloride) is bubbled through the bath in order to react with the calcium carbide.
