摘要： Steel strips are electrogalvanized with a Zn-Ni alloy deposit having the desired nickel content in a consistent manner for a long time by placing separate Zn and Ni soluble anodes in a chloride plating bath comprising major proportions of ZnCl 2 and NiCl 2 in an Ni/(Zn + Ni) ratio between 0.08 and 0.20 and a total molar amount of Zn + Ni of from 1 to 4 moles per liter, and b mole per liter of KCI and a mole per liter of NH 4 Cl as shown in Fig. 8; passing a steel strip through the bath; and introducing currents to the soluble Zn and Ni anodes in a specific ratio given by equation (2).

摘要： The present invention provides an aqueous composition and process for electrodepositing a layer of a ductile, strongly adhering, adsorptive and/or absorptive zinc coating or zinc coating comprising silicon and phosphorous on a metal substrate. The electrodeposition composition is prepared by reacting metallic silicon and zinc with phosphoric acid and an alkali metal hydroxide in the ratio of between 0,4 and 1,3 moles of alkali metal hydroxide per mole of phosphorus acid, and adjusting the solution to a pH of 1 or higher after completion of the reaction. The coating is deposited on the metal substrate by electrodeposition and comprises about 70 to 99,5% by weight of zinc, and about 0,1 to 10% by weight of silicon, and about 0,5 to 20% by weight of phosphorus. The resulting Zn/Si/P coating improves the resistance of the metal substrate to corrosion, wear, galling, stress corrosion cracking and cracking during mechanical forming operations. While essentially all metals of industrial importance may be coated, this process is especially important for ferrous metals, steels, stainless steels, copper, aluminium, chromium and titanium.

摘要： A coating comprising aluminum and at least one of the transition metals of the groups IVB, VB and VIB are prepared comprising a unique microstructure which may be a solid solution of the transition metal in an aluminide matrix or a pseudo solid solution of the transition metal in an aluminum matrix. By means of special processes a super fine distribution of the transition metal within the matrix may be obtained in the form of a metastable pseudo solid solution even though thermodynamic considerations disfavour such fine distributions. The coating may, with advantage, be applied to superalloys and be heat treated together with the substrate in order to form a stable aluminide coating comprising transition metal dispersions in an aluminide matrix. One of the preferred manufacturing processes of such coatings is the electrodeposition thereof from non-aqueous electrolytes.

摘要： Insoluble electrodes which are especially useful in the electrowinning of nickel in particular comprising an electrically conducting substrate, a barrier layer on the substrate, an electrodeposited ruthenium-iridium intermediate layer which is partially oxidized and an outer layer containing ruthenium dioxide. The ruthenium-iridium layer can usefully be electrodeposited from an aqueous bath containing a soluble ruthenium compound, a soluble iridium compound, a soluble fluoborate salt and fluoboric acid. A preferred iridium compound for use in the bath is one prepared by refluxing a diammonium hexahalo salt of iridium and sulphamic acid in aqueous solution.
