| Popis: | This research investigates the effect of normal load, alloy composition and hardness on the coefficient of friction and wear rate of Iron-Phosphorus Powder metallurgy (Fe-P P/M) alloys. The specimens were prepared from hot forged alloys (Fe-1.3wt.%P, Fe-2wt.%P and Fe-3wt.%P) were tested using Pin on disc apparatus. The wear rate increases as increasing in the normal loads. The coefficient of friction was inversely proportional to hardness. Since the phosphorus addition increases from 1.3 to 3 wt.% the volume percentage of phosphide (Fe 3 P) increased from 21 to 34vol.% which improves the hardness. The wear mechanism of the alloys is presented and discussed. |
