Original language name

Role of Al2O3 in semi-metallic friction materials and its effects on friction and wear performance

Original language description

In this work the semi-metallic friction composites with moderately increased content of Al2O3 (0, 3.4, 5.6, 9.0, and 14.6 vol%) were successfully fabricated by casting technology and their tribological properties were evaluated. The character of frictionsurfaces was confirmed by SEM. The sample with 5.6 vol% of Al2O3 offers the best tribological property among the prepared formulations, and is characterized by high and steady friction coefficient (about 0.45) and low wear. With the temperature increasing, the stibnite patches population on friction surface increases and individual steel fibers spread due to their plastic deformation to form larger primary contact plateaus. The area covered by contact primary plateaus decreases with the alumina contentincreasing.
