Investigation of friction and wear behaviors of 2024 Al and 2024 Al/SiCp composite at elevated temperatures

Tribological behaviors of Zr-based bulk metallic glass versus Zr-based bulk metallic glass under relative heavy loads

“…5(c)), wave-like patterns, deeper grooves and some peeling was mainly observed. In recent studies [22,25], a river-like vein morphology was reported probably linked to the occurrence of a highly inhomogeneous shear There are more and deeper grooves, and severe delaminations could be observed. Also, more materials was found to be piling up in the wear scar shown in Fig.…”

“…However, to allow for a wide-spread use as structural materials, BMGs should have excellent combination properties, and their friction and wear property should be considered as well. As known, a variety of factors, such as normal load [22,23], sliding velocity [24], temperatures [25], surface roughness [26,27] and surface modifications [28,29], can affect the friction and wear behaviors of crystalline materials. Because of the difference in microstructure and other properties between the crystalline material and BMG, it is necessary to study the effect of these factors on the tribological behaviors of the BMG.…”

Creep behavior and wear resistance of Al 5083 based hybrid composites reinforced with carbon nanotubes (CNTs) and boron carbide (B4C)

“…13b, delamination dramatically decreases leading to emergence of grooves on the worn surface. In fact, the increase of boron carbide particles content from 5vol.% to 10vol.% avoids establishing delamination mechanism which can be attributed to high hardness of boron carbide particles severely decreasing matrix adhesion to steel disc leading to an increase in wear resistance [34].…”

Tribology of Metal Matrix Composites

“…In some composites a significant decrease in the wear rate and coefficient of friction with temperature below the critical temperature has been reported ( Fig. 8.29) [116]. Hence, it can be inferred that the variation in tribological behavior of MMCs with temperature depends on the properties of the materials, such as mechanical properties of the materials at high temperatures.…”
