چکیده انگلیسی
Hardness and wear resistance were found to increase significantly with CNT content. The wear rate of the 5Â wt% CNT composite decreased by 78.8% compared to pure aluminum. This was accompanied by a decrease in the coefficient of friction. For samples with 5Â wt% CNT, the wear rate and coefficient of friction were found to decrease with increasing sliding speed. The SEM investigation of the worn surfaces confirmed the dominant role played by the CNTs in enhancing the wear characteristics. CNTs were observed to be either partially or fully crushed forming a carbon film that covered the surface and acted as a solid lubricant enhancing the wear behavior significantly.
