精密Nd-Fe-B永磁体的HCD法防蚀涂层

The Corrosion Resistant Coating of Precision Nd-Fe-B Permanent Magnets by HCD Processing

本文介绍了用HCD方法在精密Nd—Fe—B永磁体表面沉积耐高温高压水蒸气腐蚀涂层技术,并研究了涂层和基底近界面处的某些成分和结构特征。

In this paper, a technique about the coating on the surface of the precision Nd-Fe-B permanent magnets by HCD processing is described. The aim is that the permanent magnets are protected from any corrosion in aqueous vapour with high temperature and high pressure. The characteristics of some of the compositions and structures at the regions nearby the coating and the substrate are investigated.
