Influences of Rare Earths on Properties of Aluminium Base Bearing Alloy 稀土对铝基轴承材料性能的影响
The aluminium base bearing alloy with rare earths is studied in this paper, which recommends making alloy, coating aluminium and rolling technology of bimetal. 本文介绍了稀土铝基轴承合金的研制,合金包铝及复合轧制工艺。
Experiments show that surface treatment process of foamed aluminium is similar to that of the aluminium base alloy. 试验表明,泡沫铝的表面处理工艺与铝材的大致相同,在此工艺中泡沫铝的比表面对电流值的影响是关键因素。
The recovery is 99.0 to 102%. According to above results, new method determining copper in aluminium base alloy is established and has been applied to the determination of copper in the sample with satisfactory results. 该法灵敏度和选择性较高,精密度和准确度良好,回收率在99.0~102%之间,并已用于铝合金试样中铜的测定。
