In order to elucidate the influences of particle size of steel powder on the surface durability of induction-hardened sintered powder metal gears, the gears with three kinds of particle sizes were fatigue-tested using a power circulating gear testing machine. The three kinds of particle diameters were under 45μm, 75μm∼106μm and 150μm∼250μm, respectively. The surface durability of the gear with the smallest particle size was almost equal to that of the gear with the intermediate particle size. While the surface durability of the gear with the largest particle size was inferior to those of the other gears. The smaller the particle size became, the smaller the pore size became and the lager the pore cluster factor by fractal dimension became. The failure mode of all gears was spalling with pitting. It was understood that the pore size and the pore cluster factor were important parameters to evaluate the surface durability of the sintered powder metal gears.
