Friction and Wear Properties of Array Film of Aligned Carbon Nanorods on Anodic Aluminum Oxide Template in Vacuum

The array film of aligned carbon nanorods was prepared by catalytic chemical vapor deposition on an anodic aluminum oxide (AAO) template at 650 ℃.The morphology and microstructure of array film of aligned carbon nanorods were examined by scanning electron microscopy (SEM) and high resolution transmission electron microscope (HRTEM).The friction and wear properties of array film of aligned carbon nanorods on the AAO template in vacuum (1×10~(-1) Pa) were investigated using a ball-on-disk wear tester with array film specimen serving as the disk.The ball specimens with 3 mm in diameter were fabricated from a quenched- and-tempered steel.The array film of aligned carbon nanorods presented good friction stability and good wear resistance in vacuum.The friction coefficient first decreased with sliding velocity then increased with increase in sliding velocity,and was the minimum at 0.2 m/s.
