Study the effect of SiC content on the wear behavior and mechanism of as‐extruded SiCp/Al–Cu–Mg–Zn alloy under simulating drilling operation

Abstract

aThe Al-Cu-Mg-Zn alloys reinforced with 2.5 wt%, 4.5 wt% and 6.5 wt% SiC particles were prepared by the technology of vacuum casting, homogenization and hot extrusion. Hence, an extruded SiCp/Al-Cu-Mg-Zn with well-distributed SiC particles was obtained for the research. The effect of SiC content on the wear behavior between SiCp/Al-Cu-Mg-Zn and P110 casing steel was studied by using block-on-ring sliding abrasion tester under drilling fluid condition. The results showed that the wear rate of 6.5%SiCp/Al-Cu-Mg-Zn reduced by 80%, compared with the extruded Al-Cu-Mg-Zn alloy. Furthermore, the wear behavior of SiCp/Al-Cu-Mg-Zn was studied by using dynamic load impact tester with the silica sand used as abrasive. The results showed that the wear rate of 6.5%SiCp/Al-Cu-Mg-Zn reduced by 17%, compared with the extruded Al-Cu-Mg-Zn alloy. The overall results indicated that the 6.5%SiCp/Al-Cu-Mg-Zn could be considered as a potential drill pipe material, which has higher wear resistance compared with the Al-Cu-Mg-Zn alloy.

Mechanical and Tribological Behaviors of WAl₁₂ Reinforced 2024 Aluminum Alloy Matrix Composites

“…The tensile strength of WAl12 reinforced aluminum alloy by Al-W addition is higher than W addition [16,17]. 2024 aluminum alloy is one of best choices for aluminum alloy drilling pipe, which is suffering from tensile strength and sliding friction [18]. However, no report has been reported on WAl12 intermetallic phase reinforced 2024 aluminum alloys.…”
