The friction and wear properties of 201HT aluminum alloys and the corresponding competitive coupons were tested on an electrohydraulic
servo face friction and wear testing machine (MM-U10G). The microstructures of the competitive coupons were investigated by
scanning electron microscopy (SEM) and consequently the corresponding friction and wear mechanisms were studied. The results
demonstrated that: (1) the best competitive material of friction and wear performance of the 201HT was the 201HTC. (2) the 201HTC
modified by carbon following the initial mill for oil storage of the micro-groove to be produced, increased the corresponding lubrication
performance reduced the friction coefficient and wear rate effectively. (3) the 201HT-201HTC could obtain both better friction and wear
mainly due to the initial process of grinding following the 201HT plastic deformation occurred in the surface and the formation of a series
of re-melting welding points, whereas the 201HT material hardness would be similar to the 201HTC material hardness, which led into the
competitive material friction and wear performance improvement.
