    The invention relates to metallurgy, in particular to the search for corrosion-resistant alloys used as the base of electrodes in electrolysis.
    Insoluble metal.ic electrodes, obtained by coating a metal base with platinum group metals or their oxides, have found the form of electrodes used in electrolyzing aqueous solutions of 10 salts and aqueous solutions containing various acids.
    Pure titanium is used as the metal base.
    When using pure titanium as the base of a 15 nc electrode, the base surface can be oxidized. In addition, in some cases, the base is subjected to corrosion by acid electrolyte solutions penetrating 20 through the pores in the coating layers of the electrode. This accelerates flaking and. reduces the service life of the electrode.
    Alloy 1 for the base of the electrode is known, containing titanium and zirconium. 25
    However, this alloy has a low acid resistance and is not completely resistant from the point of view of its electrochemical strength.,.
    The closest to the invention is 30 alloy 2, containing the following components, wt%: tantalum and / or niobium in the amount of up to 30, titanium is the rest.
    However, the known alloy also does not possess sufficient corrosion and durability and cannot 5 ensure a significant lifetime of the electrodes,
    The aim of the invention is to improve the corrosion resistance of the alloy.
    The goal is achieved by the fact that a titanium-based alloy containing; The tantalum, at least one element selected by the short-circuit of the group containing niobium, additionally contains at least one element selected from the 45 group containing platinum and iridium, and the group containing niobium additionally contains zirconium in the following ratio of components, wt.% :

    Example. By the vacuum-arc melting method, materials for the base of electrodes are cast, the compositions of which are listed in the table.
    Each of the disc-shaped ingots, having a diameter of 50 mm and a thickness of 10 mm, are subjected to hot forging ttrk, annealed in vacuum for 2 hours and cut into mm plates.
    A mixture of 1 g of chloride; 1 fvdi as metallic iridium, 0.5 g of tantalum chloride as metallic tantalum and 10 ml of a 10% aqueous solution of hydrochloric acid are applied to each of the electrode bases and annealed at the air to form a metallic electrode,
    Each of the obtained electrodes is named anode and evaluated using a 15% aqueous solution of sulfuric acid for electrolysis under the following conditions: electrolyte solution temperature 90 ° 0, current density 50 A / dm.
    The service life of the electrodes is estimated by the operation of the alloys of the electrode base, by the degree of peeling of the electrode coating.
    As follows from the above data, the service life of the electrodes made from the proposed USA | significantly better the service life of electrodes from a known alloy.
