Article made by joining two members together, and a brazing filler metal

摘要

In an article, a binding layer (6) formed through a heating step exists between a permanent magnet (2) and a laminate (5) of steel plates. The binding layer (6) is formed by producing a liquid phase at the heating step from a brazing filler metal made of a rare earth element-based alloy. Diffusion areas exist between a body portion of the permanent magnet (2) and a body portion of the binding layer (6) and between a body portion of the laminate (5) and the body portion of the binding layer (6), respectively. The thickness t of each of the diffusion areas is in a range of t >/= 5 mu m. The bond strength in the article is greatly increased by the provision of the diffusion areas. $$
