为了改善某型燃气轮机机匣等中温部件的抗氧化、抗腐蚀性能，提高燃气轮机机匣等中温部件的寿命，采用适用于温度在600℃左右的国产TW－7无机磷酸盐涂层涂覆于机匣等零部件表面，研究该种涂层的硬度、结合力及对基体力学性能的影响。结果表明：国产TW－7无机磷酸盐涂层硬度与基体比较接近，涂层的结合力良好，达到23MPa左右，划格法结合力符合1级，且此种涂层喷涂后对基体的力学性能没有产生影响。

In order to improve the oxidation resistance and corrosion resistance of the medium temperature parts in a gas turbine machine such as casing, prolong the service life of medium temperature parts, domestic TW-7 inorganic phosphate coating( applicable to parts of working temperature about 600℃) was coated on the surface of medium temperature parts to research the hardness, adhesion and impact on the mechanical properties of the substrate.Results showed that: domestic TW-7 inorganic phosphate coating hardness closed to the substrate, the adhesion strength of the coating was good, has reached around 23MPa, cross cut test showed coating adhesion can be measured in accordance with level 1.The substrate after coating spraying didn't affect to the mechanical properties of the substrate.
