AbstractAn Italian company, involved in the production and marketing of innovative technologies, developed a method for the electro-deposition of n-ary metal alloys with uniform dispersion, mass ratios, and mechanic proprieties. The technology allows improved performances, reduced manufacturing costs and a simplified preliminary study on the plating bath. Commercial agreement and technical cooperation is sought for development and industrialization.DetailsAccording to this technology the co-deposition of alloys with several elements (binary-tertiary-quaternary up to seven elements) is made possible with the desired mass ratios of the alloy elements.The dispersion of the alloy elements is uniform and with the desired micro crystalline grains dimensions to achieve the target mechanical properties or electro-magnetic properties. The method allows a selective control on the deposited metals in such a way that impurities are avoided within the deposit texture. A major feature of the method, is that the preliminary study of the bath is not crucial and highly simplified. As the electrochemical compatibility of the alloy components is verified, any kind of alloy deposition is possible with the proposed method. The chemicals usable for the plating bath are related only to chemical composition of the wanted alloy depending on the desired mechanical properties of the deposit. The method makes use of common commercially available salts and complexes. Additionally the control of Hydrogen formation is obtained. Applications of the technology are the coatings (plating) either with solid and porous wall, the fabrication of self standing parts of thick layers (structural parts with mechanical strength) either with solid and porous wall; The method brings to the fabrication of high purity materials with improved performances, a dramatic reduction of manufacturing costs and of the fabrication tolerances. Innovative Aspects: Innovations: 1. The co-deposition of alloys with several components is made possible with the desired mass ratios of the alloy elements. Actual technology allows to plate not more than 3-4 elements together. 2. It allows to get uniform dispersion of the elements and desired micro crystalline grains dimensions to achieve the target mechanical or electro-magnetic properties, not always possible with the actual galvanic technology. 3. The method allows a selective control on the deposited metals in such a way that impurities are avoided within the deposit texture. 4. The preliminary study of the bath is not crucial and highly simplified, differing from the actual galvanic alloy technology that are time consuming, and large chemicals are usable for the plating bath. 5. The Materials deposited are almost any metallic alloy (Nickel based, Cobalt based alloys, Bronze, Special steels;) and the applications fields are coatings (plating) either with solid and porous wall and thick layers (structural parts with mechanical strength) either with solid and porous wall. 6. The fabrication of high purity materials with improved performances and reduced tolerances is allowed and it is a step forward in metallurgy Advantages: 1. Reduction of process and manufacturing costs; 2. Alternative metallurgic processes for fabrication of alloys, fabrication of purified alloys
