ABSTRACT:
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.
