Abstract
1419302 Coated carbon electrodes NIPKTI PO CHERNA METALURGIA 29 Jan 1973 4459/73 Heading B2E [Also in Divisions C7 and H5] A protective coating layer on a cylindrical carbon article 11 is made by burning continuously an electric arc between a layer of material on the article and a lateral electrode 2, the arc being stabilised in a magnetic field and having a current of more than 600A, the article and electrode moving helically relative to one another at a pitch of more than 10 mm and producing a helical band on the article having a width 9 of more than 10 mm when measured in a direction parallel to the axis of the article. The magnetic field is generated by a coil 1 concentric with the lateral electrode 2. The coil may be in series with the arc (Fig 1 not shown) or be supplied separately 7, 8. Hollow iron core 5 is water cooled, as is the non magnetic face 6. When the article 11 is an electrode a plurality of protective layers are applied. The layers consist of aluminium, alone or with copper, sprayed on molten followed by the arc treatment or by pastes comprising carbon or aluminium, silicon carbide (or silica), boric acid, and optionally titanium dioxide which are then arc treated. Preferably the arc treatment is carried out at a pitch of 11-12 mm and currents from 1150A to 1900A. Reference has been directed by the comptroller to Specifications 1026055 and 1151071.
