摘要
对于超硬铝合金7075,本文通过加入纳米稀土氧化物来提高其硬度。在本次实验中加入纳米稀土氧化物的含量为0.2%,原铝合金7075和改性后的铝合金7075作硬度对比,结果加入纳米稀土氧化物的铝合金7075硬度较原铝合金7075提高22.4%。在干摩擦磨损测试中,加入纳米稀土氧化物的7075铝合金磨痕宽度比原铝合金7075小。
The nanosized rare earth oxide particles were doped in 7075 aluminum alloy to improve hardness. The content of added dopant was 0.2% in aluminum alloy. Test results showed the hardness the modified 7075 aluminum alloy is improved about 22.4% compared with the raw material. In dry friction, the wear scar width of the modified 7075 aluminum alloy is smaller than that of raw material.
