PROCESS FOR PRODUCING METALLURGICAL POWDER, PROCESS FOR PRODUCING POWDER MAGNETIC CORE, POWDER MAGNETIC CORE, AND COIL COMPONENT

摘要

method for producing a powder metallurgy is , a plurality of the first binder on the surface of the first particle 10 a step of coating the first (30) , a first binder 30 to the surface , the second particles 20 having a plurality of small diameter than the diameter of the first particles 10 including a coating process . In the step of coating the second particles 20 , utilizes a second particles 20 having a particle diameter of the plurality of the 1/5 times or less the diameter of the first particles (10) . ;
