摘要

运用超音速等离子喷涂（S-APS）技术在45号钢基体表面制备多元铝青铜合金粉体涂层

为了改善结合性能

对涂层进行感应重熔处理。用XRD、SEM、EPMA分析Fe、Co、Ni、Mn等4种元素在感应重熔过程中的扩散行为。结果表明

基体中Fe在涂层中扩散距离很短;Co易固溶于Fe由涂层向基体扩散;Ni伴随Cu自涂层向基体转移;Mn向结合带处的扩散缓慢。Fe、Co以Fe3Co7等形式富集于灰色相中;Ni以NiCu、AlNi形式富集于灰色相中

Ni替代Cu形成AlNi2Mn

使Ni整体分布均匀;Mn以AlNi2Mn形式均布于涂层中。

Abstract

The multi-element high aluminum bronze coating was prepared on polished 45 steel substrate using a supersonic plasma spraying system.And the sample was treated with a high frequency induction remelting equipment in order to improve comprehensive properties of tinterface.The diffusion behaviors of Fe

Ni and Mn in the samples during induction remelting process were analyzed by XRD

SEM and EPMA.The results show that the diffusion distance of Fe in the substrate is very short.And Co can easily dissolve in Fe and diffuse from coating to substrate while the diffusion of Cu accompanies with Ni is from the coating to the substrate.The diffusion rate of Mn in interface is slow.Fe and Co can be enriched in gray phases in form of Fe3Co7.Meanwhile

Ni is slightly enriched in gray phases in the forms of NiCu and NiAl.In addition

Cu is substituted by Ni to form AlNi2 Mn

taking Ni uniform distribution.Mn is distributed evenly in the coating in form of AlNi2 Mn.
