Cu-plated Fe powder by the use of the etching waste solution is produced. Since the amount of plated Cu can be regulated, the composition of plated powder in this study is controlled Fe-50wt%Cu. As the result, there is the excellent compactibity of plated powder and it is possible to sinter at low temperature. For instance, the rattler value of 0.25% was obtained by the compacting pressure of 294MPa and the radial crushing strength was 171MPa at the sintering temperature of 973K for 3.6ks. The sintered compacts of the plated powder in comparison with mixed<BR>powder have the low dimensional change, the uniform in the pore distribution and reasonable mechanical strength. Conseqently this Cu-plated Fe powder appears to be very suitable oil-impregnated bearing. Furthermore, this sintered compact is very superior in roundness and cylindricity which are important from the standpoint of the precision of bearing.
