碱性抛光工艺中铝制品表面光泽度的表征

Glossiness Charaterization of Aluminum Product Surface in the Alkaline Chemical Polishing Processes

摘要: 以光泽度作为铝合金制品表面粗糙度的评价指标之一，进行碱性化学抛光实验。采用光泽度仪测试铝合金表面的光泽度，并通过原子力显微镜测试其粗糙度。实验结果表明铝合金表面光泽度越高，其表面粗糙度则越低，其中在抛光基础液加入钼酸铵40 g/L的条件下，5052铝合金光泽度可达299 Gs，对应的表面粗糙度为6.395 nm。

Abstract: Taking glossiness as one of evaluation index of surface roughness for aluminum alloy products, alkaline chemical polishing experiments were carried out. The glossiness of the surface of the aluminum alloy was tested by using a gloss meter and its roughness was measured by an atomic force microscopy. The experimental results showed that the higher the surface gloss of aluminum alloy, the lower the surface roughness. 5052 aluminum alloy glossiness could reach 299 Gs, and the corresponding surface roughness was 6.395 nm, while 40 g/L of ammonium molybdate was added to the polishing base liquid.
