摘要
PURPOSE:To remarkably improve corrosion resistance and film thickness uniformity insufficient in conventional plating in a magnet containing rare earth elements and iron as main ingredients. CONSTITUTION:An R-TM-B series permanent magnet having improved corrosion resistance and film thickness uniformity comprises double layers formed of an electrolytic Cu-plated layer and an electrolytic Ni-plated layer on the surface of the R-TM-B series permanent magnet substantially containing by weight 5-40% of R (R is a combination of one or more types of rare earth elements including Y), 50-90% of TM (TM is transition metal containing Fe as a main ingredient) and 0.2-8% of B (boron).
