    • A regenerative-cooling combustion chamber for a liquid-propellant rocket engine coated by nickel and chrome and a coating method thereof are provided to improve abrasion resistance, heat resistance, and corrosion resistance by forming an electroless nickel layer and an electrolysis chrome layer inside a combustion chamber. A regenerative-cooling combustion chamber for a liquid-propellant rocket engine coated by nickel and chrome comprises: a combustion chamber inner coat(130) equipped with a cooling channel; and a combustion chamber outer coat(110) coupled with the single-side of the combustion chamber inner coat. The electroless nickel layer and the electrolysis chrome layer are successively coated on the other side of the combustion chamber inner coat. The thickness of the electroless nickel layer is 150~250 micron. The thickness of the electrolysis chrome layer is 100~200 micron.
    • 提供了一种用镍和铬涂覆的液体推进剂火箭发动机的再生冷却燃烧室及其涂覆方法,以通过在燃烧中形成无电镀镍层和电解铬层来改善耐磨性,耐热性和耐腐蚀性 室。 用于由镍和铬涂覆的液体推进剂火箭发动机的再生冷却燃烧室包括:配备有冷却通道的燃烧室内涂层(130) 以及与燃烧室内涂层的单侧联接的燃烧室外涂层(110)。 无电解镍层和电解铬层依次涂覆在燃烧室内涂层的另一侧。 化学镀镍层的厚度为150〜250微米。 电解铬层的厚度为100〜200微米。
