The invention relates to a metal burning testing method, and in particular to the technical field of metal ablation. The metal burning testing method includes the steps that a metal sample (16) is prepared; the metal sample (16) is placed in a burning kettle (1); an igniter (6) is connected; vacuumizing and oxygen-containing gas pressurization operation are conducted on a cavity body of the burning kettle (1); the metal sample (16) is burned; data are collected after complete burning; after the igniter (6) stops burning, a power source is turn off, the burning kettle (1) is depressurized, anda testing device is cleaned; and finally the length of the remained mental sample (16) is measured. According to the metal burning testing method, the burning process of the metal materials is observed in real time, the conditions, such as the temperature and the pressure, of metal burning can be precisely obtained, safety of the testing process is guaranteed, and thus a large amount of analysis of tests and systems can be conducted.
Description
technical field [0001] The invention relates to the technical field of metal ablation, in particular to a metal material combustion test method. Background technique [0002] Under the conditions of high temperature, high pressure, and oxygen-enriched conditions, metal materials undergo a violent chemical reaction that is similar to the ignition and combustion of wood, resulting in a reduction in the volume of the metal material, melting of the surface, and even severe corrosion and ablation. Metal burns. In some extreme conditions, this has become an essential factor leading to the failure or even explosion of some high-performance aerospace engines, such as supersonic and supersonic ramjet engines, liquid oxygen / kerosene and hydrogen / oxygen engines, and high-firing weapon systems one. [0003] For a long time, people have been very concerned that metal structural materials, especially non-flammable steel, nickel-based, molybdenum-based alloy materials, will also ignite a...
