Wear Behavior of Extruded Nano-SiCp Reinforced AZ61 Magnesium Matrix Composites

Abstract EN

The wear behavior of extruded nano-SiC particulates reinforced AZ61 magnesium matrix composites fabricated by ultrasonic method was investigated with wearing test machine, electronic balance, and scanning electron microscopy (SEM).

The results show that, at the sliding speed of 0.5 m/s or 1 m/s, the extruded composites exhibit superior wear resistance over the matrix with the rise of wear load.

At the high load, the softening and melting of composites are delayed to higher loads and speed because of their higher thermal stability.
