纳米硬质微粒对枪管内膛破坏机理的研究

Mechanism of nanometer hard particles destroying gun barrel bore

利用5.8 mm弹道枪作为试验平台,通过在发射药内添加微量纳米硬质微粒的方法进行对比射击试验。结果表明,纳米硬质微粒对枪管内壁有极大的破坏作用,间接证明硬质火药残渣对枪炮管存在一定的破坏作用,并确定其破坏模式。可为今后的身管延寿技术研究提供一定的借鉴作用。

The 5.8 mm ballistic gun was chosen as a firing test platform. Trace of hard particles was added into propellant in the test. Results of test show that hard particles can badly destroy the inner bore of gun barrel. Also the result of test indirectly proves that hard leavings of propellant can destroy gun barrel. The destroy mode was studied and conclusions can provide some helpful references to research of life extending technology of gun barrel.
