Being the iron basic powder blend for metal ceramic and the iron basic

摘要

PROBLEM TO BE SOLVED: To provide an iron based powdery mixture for powder metallurgy which has reduced componential segregation, and has excellent fluidity, compressibility and extractibility in the range form an ordinary temperature to a warm temperature.;SOLUTION: A mixed layer of graphite particles with a particle diameter of 0.01 to 10 μm and lubricant particles with a particle diameter of 0.01 to 10 μm is formed on the surfaces of iron based powder and auxiliary raw material powder.;COPYRIGHT: (C)2004,JPO&NCIPI
