HARMONIC STRUCTURE POWDER FOR POWDER METALLURGY, MANUFACTUREING METHOD THEREOF AND POWDER COMPACTING METHOD USING HARMONIC STRUCTURE POWDER

摘要

There is the particle formed on a coating surface to want the powder metallurgy of basic material although there is coating intensity to compare basis material for powder metallurgy harmonic structure. Therefore, it wears, processing pressure, the processing time substantially reduces, when molding manufactures, thus the raising of the productivity of high-density powder metallurgy product. Contain particle according to the powder of harmonic structure powder and compare the superficial layer with low mechanical strength with inner core by inner core, wherein superficial layer is to pass through heat treated powder. ;The 2016 of copyright KIPO submissions
