Definitions
- My invention refers to the plating of metal and more especially to the As is well known to those skilled in the art tungsten bronzes and molybdenum bronzes are compounds which were hitherto produced by reducing acid tungstates and acid molybdates. respectively, at high temperature. It is thus possible to produce for instance barium tungsten bronze BaW O or sodium molybdenum bronze Na Mo O More detailed descriptions of these compounds can be found in. many text books,for instance in Smithells Tungsten (London 38-39, where tungsten bronzes are defined as havin the constitution R OWO2nl/VO wherein R is an alkali-forming or an alkaline earth or similar metal, while 01. is an integer. Thus tungsten and molybdenum bronzes can be defined by the formula R OXO nXO,, wherein X is tungsten or molybdenum.
- coatings consisting of these and similar bronzes can be produced in a simple manner on any metallic body.
- electrolysis According to the experiences hitherto made the electrolizing of solutions of normal orthotungstates 'or orthomolybdates.results in the production of tungstenoxides or molybdenum oxides of a low stage of oxidation.
- cal process can be conducted in such manner that the bronzes obtained are precipitated on the metal body forming the cathode in the form of a firmly adhering and altogether uniform coating.
- This coating can be produced with particular advantage from solutions of the alkali metal salts and alkaline earth metal salts of meta-or polytungstic acid or metaor polylnolybdic acid. I prefer using watery solutions of barium meta-tungstate BaW O +9HO or strontium. meta-tun state SrW O +9H O. By simultaneousfy varying the concentration of the solutions and thecathodic current density bronze coatproduced in the same period of time.
- Example 1 A metal body which may for instance have a surfacearea of 100 mm is placed in a 70% solution of barium meta-tungstateheated to C. and inserted as cathode in an electrolytic circuit comprising an anode consisting of a. precious metal.
- I now apply to the electrodes -a.voltage such that the intensity of the current flowing through the solution corresponds to vD,'. 1O0 milli amp. per cm of cathodic current.
- the electrolytical process is carried through with acurrent of 0,.1 amp.
- the electrolytical process results in the almost immediate formation of a blue coherent bronze coating.
- the metal body is now removed from the solution, rinsed with hot water and dried.
- the solution from which the barium molybdenum bronze is precipitated can be produced for instance in the following manner: a watery sodium meta molybdate solution is treated with a solution of BaCl to produce the corresponding barium meta molybdate, which is then suspended in distilled water, dilute hydrochloric acid being added until the barium meta molybdate has been dissolved.
- E wample 3 The metal body to be coated'is placed in a solution of strontium meta-tungstate having a specific density of 1, l and inserted as cathode in the electrolytic circuit, any desired metal body, for instance a piece of tungsten, being used as anode.
- a current corresponding to a cathodic current density of 250 milli amp. per cm is allowed to flow through the solution.
- the current is interrupted, the metal body withdrawn, washed with hot water and dried.
- the new method thus allows plating metal bodies of all descriptions, for instance bodies consisting of tungsten, molybdenum, platinum or nickel with one of these bronzes. Owing to their advantageous properties the metal bodies plated in this manner are particularly adapted for the production of oxide cathodes.
- I claim 1 As a new product a metal body electroplated with a compound having the formula R OXO nXO wherein X is tungsten or molybdenum, while B is an'alkali-forming or an alkaline earth or similar metal and n is an integer.
- the method of plating metal bodies comprising placing the body to be plated in a solution of a salt ofthe group of acids constituted by metaor poly-tungstic and bodybdic acids, inserting said body as cathode in an electric circuit and causing an electric current to act on the solution.
- the method of plating metal bodies comprising placing the body to be plated in a solution of an alkali metal salt of the group of acids constituted by metaor poly-tungstic and molybdic acids, inserting sald body as cathode in an electric circuit and causing an electric current to act on the solution.
- the method of plating metal bodies comprising placing the body to be plated in a solution of an alkaline earth metal salt of the group of acids constituted by metaor EMIL "IHEISZ.
