摘要：利用非晶Al-Ce-Fe粉体，通过冷喷涂方式在AA7075铝合金基体上制备Al-Ce-Fe非晶合金镀层。在形成镀层过程中，冷喷涂对非晶粉体形成的镀层没有导致明显的晶化，能形成均匀紧实的连续涂层，硬度可达HV228，在0.6 M NaCl中性溶液中耐蚀性较AA7075铝合金基体提高两倍，在0.01 M NaCl中性溶液中耐蚀性较AA7075铝合金基体提高五倍。实验表明，冷喷涂技术形成的非晶Al-Ce-Fe镀层具有优异的抗蚀性。

Abstract：Cold gas dynamic spraying was employed to deposit Al-Ce-Fe amorphous coating on AA7075 aluminum alloy substrate. The cold spraying technique can retain the deposited alloy coating from amorphous alloy powders amorphous to form a uniform, compact and continuous coated layer. The hardness of the coating attains to HV 228. The corrosion resistance of the as-deposited Al-Ce-Fe amorphous coating amounts to twice and five times higher thanthat ofAA7075 aluminum alloy in 0.6 M NaCl and 0.01M NaCl solutions, respectively. The result demonstrates that the Al-Ce-Fe amorphous coating deposited by cold spraying possesses excellent corrosion resistance.
