摘　　要：对镁合金表面冷喷涂快凝Zn-Al合金粉末工艺进行了研究,观察了涂层微观组织,并分析了涂层与基体之间的结合,测定了涂层的硬度和涂层与基体的结合强度。结果表明,采用冷喷涂技术制备的快凝Zn-Al合金粉末涂层组织致密,基体与涂层的结合处只产生塑性变形并且无熔化现象,涂层硬度比基体硬度显著提高。The microstructure,hardness of rapidly solidified Zn-Al powder coating on surface of magnesium alloy by cold spray method as well as the bonding strength between the coating and the matrix were investigated,and only the bonding between the coating and the matrix were understood.The result shows that the coating with sound microstructure can be obtained,and only the mechanical bonding between the coating and the matrix can be observed.The hardness of the coating is greatly higher than that of the matrix alloy.
