Conclusions
-
1.
A study was made of a simplified method of manufacture of sintered samarium-cobalt permanent magnets based on the use of “overmilled” starting SmCo5 powders.
-
2.
It is shown that the key critical parameter in the simplified process is the total amount of the rare-earth component in the starting charge.
-
3.
The process investigated ensures a reliable reproduction of magnetic characteristics of sintered SmCo5 permanent magnets within the following ranges: Br=8400±250 G,BHc=6650±384 Oe, and (BH)max=15.2±0.93 MG-Oe. The maximum level of magnetic energy attains 23 MG-Oe.
