Embodiment Construction

[0020] As shown in the accompanying drawings, the present invention provides an anode high temperature protection method, which includes the following steps: adding positive electricity to the shell 3 that needs to be protected, and simultaneously applying negative electricity to the sacrificial electrode 1 that is automatically renewed or easily replaced or needs to be heated most on the substance, or use an electron gun to emit electrons away from the shell 3 to be protected so that the shell 3 to be protected is positively charged; the positive charge applied by the shell 3 to be protected repels the high-temperature plasma Positive ions, so as to avoid positive ions impacting the shell 3 that needs to be protected to produce a heating effect. At the same time, the positive ions flying away at high speed hit neutral molecules or atoms, so that they become positive ions before hitting the shell, and are absorbed by the positive ions of the shell. Charges are repelled away to ...

Abstract

The invention relates to an anode high temperature protection method and protection device. A positive charge is applied to a shell or a component, meanwhile, a negative charge is applied to a self-renewing or easy-to-replace sacrificial electrode or a substance most in need of heating, or electrons (the negative charge) are emitted to a place far away from a spacecraft by an electron gun, and thespacecraft loses part of the negative charge and gains the positive charge. Positive ions in a high-temperature plasma is repelled by applying the positive charge to the component or shell needing tobe protected, therefore the heating of the positive ions in the high-temperature plasma to the component or the shell is effectively reduced, and the purpose of high temperature protection is achieved. The anode high temperature protection method and protection device are suitable for protection for high temperature generated by friction between the spacecraft shell and atmosphere in the recoveryprocess of the spacecraft, and meanwhile is also suitable for high temperature protection of the inner parts of a rocket engine, a turbine engine and a high-temperature furnace.

Description

technical field [0001] The invention belongs to the technical field of high temperature protection, and in particular relates to an anode high temperature protection method and a protection device. Background technique [0002] Due to aerodynamic heating during the re-entry stage of the return capsule in the aerospace field, the friction between the spacecraft shell and the atmosphere will generate high temperatures. If there are no proper protective measures, the high temperature will not only cause serious damage to the spacecraft shell, but may also damage internal components, and even endanger the lives of astronauts. In addition, some components of rocket engines, turbine engine nozzles, combustion chamber walls, turbine blades, and other high-temperature furnaces and reaction vessels used in industrial production are also exposed to high temperatures and require appropriate protection. [0003] In the prior art, most of the high-temperature protection technologies for...
