鉄系焼結鋼の被削性に及ぼすCa複合酸化物添加量の影響 Effect of Complex Calcium Oxide Admix Ratio on Machinability for Sintered Steel
This paper reports the effect of complex calcium oxide named KSX admix ratio on mechanical properties and machinability under various cutting-speeds for Fe-Cu-C sintered steel. KSX improved machinability without deterioration of mechanical properties up to 0.3mass% addition. The flank wear of 0.1mass% KSX reduced by 70% compared with base material at a slower cutting speed of 150m/minute. As for a faster cutting speed of 250m/minute, the flank wear of 0.3mass% KSX reduced by 65% compared with base material. 0.2mass% or more addition of KSX restrained crater wear up to 20 minutes of cutting time.
