COATING FORMULATION AND APPLICATION OF ORGANIC PASSIVATION LAYER ONTO IRON-BASED RARE EARTH POWDERS
摘要：
The present disclosure relates to coating formulations for neodymium-iron-boron type magnetic powders manufactured from rapid solidification processes for the purpose, inter alia, of corrosion and oxidation resistance when exposed to aggressive environments. The coating formulation preferably contains an epoxy binder, curing agent, an accelerating agent, and a lubricant. By incorporating coupling agents and optionally, other specialty additives with the magnetic powder and the organic epoxy components, additional oxidation and corrosion prevention, enhanced adhesion and dispersion between the filler and matrix phases can be achieved. This disclosure relates to all such rare earth-transition metal-boron (RE­TM-B) powders produced by rapid solidification and encompasses both the bonded magnet products that include combinations of the materials mentioned and the application processes.
摘要（中）：

本公开涉及一种用于从为宗旨快速凝固工艺，除其他外，耐腐蚀和耐氧化性的制造当暴露于侵蚀性环境的钕 - 铁 - 硼型磁粉末涂料配方蒸发散。 涂布制剂优选包含环氧粘合剂，固化剂，在促进剂，和润滑剂。 通过将偶联剂和任选的其它特殊添加剂与填料和基质相之间的磁性粉末和有机环氧树脂的部件，附加的氧化和防腐蚀，提高粘合和分散​​都可以实现。 本发明涉及所有寻求稀土 - 过渡金属 - 硼（RE-TM B）由快速凝固生产的粉末和既包括粘结磁体制品确实包括所提及的材料和应用方法的组合。
