Problems solved by technology

Therefore, when the anti-oxidation test of the sample is carried out by the traditional process, the highest anti-oxidation test temperature of the sample is consistent with the anti-oxidation temperature of the heating element, or is lower than the anti-oxidation temperature of the heating element. High requirements greatly increase the cost of the test, and at the same time, the oxidation of the heating element will also affect the test

Abstract

The invention belongs to the field of material performance detection and particularly relates to a superhigh temperature oxidation resistance testing platform which comprises a vertical type furnace body and a furnace door at the upper end of the furnace body; the lower part of the furnace body is provided with a vacuum device and a protective gas replenishment device; the furnace body is internally provided with an insulating layer; the top of the insulating layer is provided with an insulating door component; the middle part of the insulating layer is provided with a supporting plate used for placing a sample piece; the supporting plate is connected with an ejection device; the ejection device can eject the insulating door component; and a detection instrument is arranged above the furnace door. By adopting the superhigh temperature oxidation resistance testing platform provided by the invention, a heating element heating environment is separated from an oxidation test environment; during heating, protective gas rushes into the furnace body as a gas protection environment; after heating is finished, the heated sample piece is rapidly moved from the gas protection environment intoan oxidation environment, so that the high-temperature sample piece is subjected to oxidation at the oxidation atmosphere, the heating element is still in the gas protection environment to be protected from not being oxidized, the service life of the heating element is greatly prolonged, the test cost is reduced, and the superhigh temperature oxidation resistance testing platform has better market value.

Description

technical field [0001] The invention belongs to the field of material performance detection, in particular to an ultra-high temperature oxidation resistance test platform and a test method. Background technique [0002] With the development of industrial technology, the aerospace industry and missile technology have developed rapidly. The development of the aerospace industry requires materials with high temperature resistance, harsh environment resistance, and oxidation resistance. Ceramic materials, carbon fiber materials, and composite materials. The special properties of high temperature and oxidation resistance have been applied more and more, and these properties are very suitable for spacecraft and high-speed missiles. If ceramic materials, carbon fiber materials, and composite materials are to be applied, the detection equipment and methods of materials must first be solved question. [0003] The traditional test method is to heat the sample in the furnace, keep it ...
