This study measured the coefficients of friction on several lubricants for powder metallurgy with horizontally both- way sliding friction tester. We obtained the results that static coefficients of friction on those powder lubricants were from 0.21 to 0.45, and those kinetic coefficients of friction were from 0.13 to 0.25. Furthermore, the relationship between coefficients of friction and ejection pressures on several powder lubricants showed that low kinetic coefficient of friction tended to below-ejection pressure, on mixed-type lubricants. The relationship between coefficients of friction and green density on them showed that low-static and kinetic coefficients of friction tended to be high-green density.
