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。

Abstract

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.
