A METHOD OF IMPROVING THE MAGNETIC PROPERTIES OF POWDER METALLURGICALLY PRODUCED SOFT MAGNETIC COMPOSITE COMPONENTS

摘要

The present invention concerns a method of improving the properties of powder metallurgically produced SMC compacted body consisting of a soft magnetic material of insulated powder particles and an organic lubricant, to a stress relieving heat treatment in a furnace until the component has reached a temperature of at least 400 °C in an oxygen containing atmosphere having a CO content is less than 0.25 % by volume.
