Titanium carbide
Scope Carbide — titanium electrodes. (TiC)
Titanium carbide provides a basis superhard refractory materials, industrial arc lamp electrodes, special tools. It is used as an additive to graphite or his substitute. It is also used for:
— Covers of thermocouples;
— Heat-resistant electric screen;
— Housings crucibles and boats, vacuum evaporation of low-melting metals (such as tin, silver and copper);
— Reinforcement of the heat exchange;
— Abrasive treatment of metals and non-metals, stones, semiconductors, glass, etc.,.
— Filler diamond tools.
TiC is used as an electrode in the electrolysis in a mercury cathode pair. With TiC-sodium amalgam is applied to the electrode. TiC-electrodes are used in the electrolysis of an aqueous solution at-electric underwater cutting steel — thus allowing the titanium carbide is 6−10 times lower electrode consumption as compared with conventional electrodes.
Features of operation
When cutting steel is characterized by light excitation of the arc, steady burning, so the cut is obtained high quality. When the additive material in the graphite electrodes of titanium carbide, increases the efficiency of electrolysis. If you increase the carbon content of the TiC-electrode to 30%, then it decreases stress and release of free O 2 and H 2. The current density will be 10,2 — 10,4 A / cm 2. Exceeding 30% fraction of carbon in the electrode does not lead to a further reduction of overvoltage. When welding fusible alloys, such as copper or magnesium-based, the use of TiC-electrodes is almost impossible. Refractory tubular electrodes and crucibles are indispensable for vacuum evaporation of low-melting metals. For the coating of graphite electrodes of electric furnaces used alloys of TiN — TiC — Cr.
Production
TiC for manufacturing electrodes has the following characteristics: Ti commonly from 79.2 — 80%; C St. from 0.1 to 0.2%; C Society. from 19.4 to 20.2%; Fe 0.1 to 0.6%.
Produced following fractions of titanium carbide: F — 320, F360, F400, F500, F600, F800, F1000, F1200.
Shipments of titanium alloys normiroany 19 GOST 807−74.
