Technical field
The present invention relates to titanium alloy tube to prepare technical field, more particularly to a kind of high-temperature titanium alloy pipe.
Background technology
Titanium alloy belongs to alloy in lightweight, has the characteristics that specific strength is high, specific modulus is high, structural behaviour is excellent, titanium alloy is close
Degree is only the 58% of steel, therefore is widely used in the fields such as oil, chemical industry, space flight.
Existing titanium alloy temperature in use is typically below 600 DEG C, when titanium alloy is in more than 650 DEG C of temperature, its intensity
Difference, inoxidizability deficiency, so tubing made of existing titanium alloy with temperature typically can only less than 600 DEG C, and use
It is higher that high-temperature titanium alloy prepares cost.
The content of the invention
The present invention solves the technical problem of a kind of high-temperature titanium alloy pipe is provided, adhere on common alloy of titanium outer wall
Have painting high-temperaure coating, common alloy of titanium pipe is used at a higher temperature, at the same improve titanium alloy tube intensity and
Inoxidizability, and it is low to prepare cost.
In order to solve the above technical problems, one aspect of the present invention is：A kind of high-temperature titanium alloy pipe, institute are provided
Stating titanium alloy tube includes titanium alloy body, is sprayed on the high-temperaure coating of the external wall surface of the titanium alloy tube, the titanium alloy
Body is that the high-temperaure coating is to be sprayed on the titanium using silester based high-temp-resistant coating using made of titanium magnesium alloy
Drying obtains again on alloy outer surface of tube body, material composition and its quality that the silester based high-temp-resistant coating includes
Percentage is：Ethyl polysilicate 35%-40%, silica flour 18%-25%, aluminum oxide 8%-12%, coalescents 4%-8%, remaining is
Water.
In a preferred embodiment of the present invention, the drying temperature after the silester based high-temp-resistant coating spraying is
180-200℃。
In a preferred embodiment of the present invention, the thickness of the high-temperaure coating is 8-20mm.
In a preferred embodiment of the present invention, the highest of the high-temperaure coating is resistant to temperature as 1950 DEG C.
The beneficial effects of the invention are as follows：The present invention sprays silester based high-temp-resistant on the outer wall of common titanium magnesium alloy pipe
Coating, high-temperaure coating is formed on the outer wall of titanium magnesium alloy pipe after drying, enables titanium magnesium alloy pipe used above at 600 DEG C,
The intensity and inoxidizability of titanium magnesium alloy pipe are improved simultaneously, and it is low to prepare cost.
