MANUFACTURING METHOD OF COMPOUND SOFT MAGNETIC MATERIAL HAVING HIGH STRENGTH AND HIGH SPECIFIC RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a compound soft material having high strength and high specific resistance.;SOLUTION: A plasma processing is performed for previously applying liquid where one type or two or above types among polyether sulfone, polyphenylene sulphide, polyamideimide, polyimide and silicone resin and polytetrafluoroethylene are dissolved or distributed on a surface of iron powder or phosphate coating iron powder and drying it. 0.1 to 1.5 mass% of fluororesin powder is added and mixed to phosphate coating iron powder to which the plasma processing is performed. Mixed powder is formed, mixed powder is compressed and molded, and heat treatment is performed on it at a temperature of 320 to 450°C.;COPYRIGHT: (C)2006,JPO&NCIPI
