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.
