摘要
Recyclable aluminum after machining was used to make composites using the SPS method. Due to the SPS method, it was possible to obtain the sinters practically without pores. Three types of composites Al + SiC and hybrid composites such as Al + (WC + 12Co) and Al + [SiC + (WC + 12 Co)] were produced. Their density, resistance to friction wear and surface topographic parameters have been determined. Based on the results, it has been shown that in the case of hybrid sinters, better tribological characteristics compared to composites reinforced with SIC particles only can be obtained. It was also shown that the friction coefficient primarily depends on the difference between the hardness of the pin and the disc. The greater difference in hardness causes the values of the friction coefficient to be higher.
