Effect of WC Grain Size of Ultrafine WC-Co Cemented Carbide on its Friction and Wear Properties AITranslate
Abstract AITranslate
In order to study the effect of WC grain size of ultrafine cemented carbide on its friction and wear properties, ultrafine cemented carbides with the average WC grain sizes of 0.25 μm, 0.35 μm and 0.50 μm were prepared by different sintering processes.The alloys were characterized and analyzed by density ba-lance, hardness tester, friction and wear tester, 3 D contour scanner and scanning electron microscope.The results show that the relative density and hardness of the alloys decrease with the increase of WC grain size.The alloy with an average WC grain size of 0.25 μm has high hardness, can effectively resist the effect of grinding balls during reciprocating friction, and has a shallow depth of wear scars, showing good wear resistance.When the average WC grain size increases to 0.35 μm, the penetration depth of the grinding ball significantly increases, and the wear resistance of the alloy decreases.Continuing to increase the average WC grain size to 0.50 μm, the hardness of the alloy continues to decrease, some broken WC particles appear in the wear morphology, the penetration depth of the grinding ball further increases, and the wear resistance is the worst.
