TITANIUM MATERIAL, THE METHOD OF ITS PRODUCTION AND THE EXHAUST PIPE Russian patent published in 2006 - IPC C23C2/12 C23C2/26 C23C2/38 C23C30/00 

FIELD: metallurgy; methods of production of titanium materials.

SUBSTANCE: the invention is pertaining to the field of metallurgy, in particular, to production of titanium materials intended for manufacture of the exhaust pipes of the transportation vehicles. The invention offers the titanium material, the method of its production and the exhaust pipe made of the titanium material. The titanium material contains a substrate material made out of a pure titanium or a titanium alloy and aluminum-containing layer formed on the surface of the substrate material. The aluminum-containing layer is at least partially formed on the surface of the substrate material and has a depth of no less than 1 micrometer, contains no less than 90 mass % of aluminum or aluminum and silicon. At that the content of silicon makes 1-20 mass % from the total of aluminum and silicon. The method provides for formation of the aluminum-containing layer on the substrate material out of the pure titanium or the titanium alloy. The aluminum-containing layer on the substrate material is formed on the substrate material with the help of the coating application by means of the substrate material dipping in the coating application bath with a melt of aluminum and withdrawal of the substrate material at rate of 1 cm/s. The technical result is production of the titanium material with the high oxidation resistance.

EFFECT: the invention ensures production of the titanium material with the high oxidation resistance.
