    • A process for treating surfaces of rare earth metal-based permanent magnets, comprising removing an oxide layer formed on a surface of each of the permanent magnets using a blasting apparatus. The apparatus comprises a tubular barrel formed of a mesh net for accommodation of work pieces and supported circumferentially outside a center axis of a support member rotatable about the center axis, and an injection nozzle disposed to inject a blast material against the work pieces from the outside of the tubular barrel, wherein at least one of the tubular barrel and the support member is detachably mounted. The process further comprises removing the tubular barrel or the support member from the blasting apparatus and attaching the tubular barrel or the support member to a vapor deposited film forming apparatus, where a metal film is formed on the surface of each of the permanent magnets by a vapor deposition process.
    • 一种用于处理稀土金属基永磁体的表面的方法,包括使用喷砂装置除去形成在每个永磁体的表面上的氧化物层。 该装置包括由网状物形成的管状筒体,用于容纳工件,并且围绕中心轴线可围绕支撑构件的中心轴线周向地支撑;以及喷嘴,其设置成将喷射材料从外部喷射到工件上 其中管状筒和支撑构件中的至少一个可拆卸地安装。 该方法还包括从喷砂设备中取出管状筒体或支撑构件,并将管状筒体或支撑构件附接到蒸镀膜形成设备,其中通过一个永磁体的表面上形成金属膜 气相沉积工艺。
