焼結体気孔中に残留する黒鉛による鉄系焼結材料の被削性改善
The effect of graphite retained in the pore sites of sintered steels on machinability was investigated. Sintered steels containing retained graphite were obtained by sintering green compacts made from sulfur-containing iron powder with copper and graphite. Retained graphite in the pore sites of sintered steels in amounts of 0.1 to 0.3wt% resulted in 10 times longer drilling tool life and no significant impact on tensile strength.
