Problems solved by technology

The traditional sample table cannot meet such harsh conditions, and there are shortcomings such as excessive internal thermal stress, which makes the sample table fragile and non-reusable during the test.
And more importantly, the traditional sample stage cannot arbitrarily change the angle of the sample during the experiment, which has obvious shortcomings in terms of experimental diversity and flexibility.

Abstract

The invention discloses a multi-dimensional tunable carrying device applicable to a high-vacuum superhigh temperature environment. The multi-dimensional tunable carrying device comprises a vacuum cavity, a high-temperature resistant bracket, a water-cooling table and a movable control system. The vacuum cavity is located in an operating platform. The upper end of the high-temperature resistant bracket is in direct contact with a sample, and the lower end of the high-temperature resistant bracket is arranged in a water-cooling table groove. The water-cooling table is arranged in an X-Y direction movable platform groove, and then is integrally fixed to a connecting flange. The movable control system can be used for controlling the sample to move in the X-Y direction and in the Z direction. The device can be used in the high-vacuum environment with the temperature being below 1800 DEG C, and has the advantages of being suitable for various heating modes, high in thermal insulation efficiency, stable in chemical property, tunable in multiple dimensions and the like.

Description

technical field [0001] The invention relates to a carrying device, in particular to a multi-dimensional adjustable carrying device which can be used in a high vacuum and ultra-high temperature environment. Background technique [0002] The severe aerodynamic and thermal environment faced by hypersonic vehicles poses a great challenge to the high-temperature mechanical properties of heat-resistant materials. Due to the high cost of online service testing of materials, the characterization and evaluation of heat-resistant materials requires a series of ground simulation tests. Research on the catalytic and oxidation properties of high-temperature materials needs to be carried out under high-vacuum and high-temperature experimental conditions, so a supporting device that can be used in high-vacuum and ultra-high-temperature environments is needed to carry samples. Special experimental conditions require that the supporting device can withstand a high temperature of at least 18...
