中文摘要：
铁 aluminide 金属间化合的涂层从高使用速度弧喷洒的 FeAl/Cr3C2 cored 电线(HVAS ) 被准备技术。侵蚀；HVAS 的腐蚀性质喷洒了 FeAl/Cr3C2 涂层被调查。结果证明在 30 °的冲击角度的侵蚀多于 90 °的。涂层的侵蚀抵抗随温度的增加被提高。涂层比底层有一个更好的侵蚀电阻。侵蚀在 450 ° C 上面从可锻的行为改变了到易碎的行为。在高温度，侵蚀电阻比在低温度的那些优异；房间温度。涂层比底层有高得多的腐蚀性质。温度在涂层的腐蚀抵抗上有小效果；涂层输的腐蚀随腐蚀时间的增加慢慢地增加了。喷洒 HVAS 的 FeAl/Cr3C2 涂层展出了高契约力量；坚硬。
英文摘要：
Iron aluminide intermetallic coatings were prepared from Fe-Al/Cr3C2 cored wires using High Velocity Are Spraying （ HVAS ） technology. Erosion and corrosion properties of HVAS sprayed Fe-Al/Cr3C2 coatings were investigated. Results show that the erosion at impingement angle of 30°is more than that of 90°. The erosion resistance of coatings was enhanced uith the inereaase of temperature. Coatings had a better erosion resislance than substrwles. The erosion changed from ductile behariors to brittle behaviors above 450℃ . At high temperature, the erosion resistances were superior to those at low temperwlure and roonl temperwlure. Cowlings had much higher corrosion properties than substrates. The temperature had a little effect on the corrosion resistance of coatings ; The corrosion losing of cowlings increased slowly with the increase of corrosion time. The HVAS-sprayed Fe-Al/Cr3C2 coatings exhibited a high bond strength and hardness.
