Abstract

In this report, a study was made on the influence which the compound ratio of sintering annexes MOS2 and FeMn contained in porous sintered metal has on the characteristics of wear resistance of iron-based porous sintered metal ring, with a view to improving the wear resistance characteristics of spinnig ring.First, we specified 5 different kinds of compound ratio and conducted abrasion tests to check the relationship among compound ratio, amount of wear, surface roughness and gas permeability of ring.According to test results, the best characteristics of waer resistance were obtained when the compound ratio of MoS2in the sintering annexes was 60∼67%.Next, this newly developed ring (66.7% MoS2, 33.3% FeMn) and conventional standard ring (100% MoS2) were submitted to actual load operation and the changes of amount of wear, gas permeability and surface roughness of both rings against the operating time were measured and compared with each other. From the results of this experiment, it has been found that the former is superior to the latter in wear resistance characteristics and that this superioirty comes from the fact that the pores of the newly developed ring are shaped in way to better lubricate the ring surface.
