摘要

研究了不同表面预处理方法对AA 6063铝合金阳极氧化性能的影响。在预表面处理方法的范围内，确定了酸性溶液的浓度和处理时间。酸性溶液用氢氟酸(HF)和硝酸(HNO3)测定。并采用Gresoff LIM-5 LV化学剂，在不同浓度和工艺时间下进行脱脂处理。研究了酸性溶液对铝样品的腐蚀作用。当HF浓度为1.0%，HNO3浓度为3.2%，工艺时间为10 min时，刻蚀效果最佳。当Gresoff LIM-5 LV浓度为1.0%时，处理时间为12分钟，表面性能最佳。然后用180 g / L硫酸(H2SO4)和18伏(V)进行阳极氧化。通过SEM分析、粗糙度、光泽和厚度测试来检测最终铝型材的表面形貌。

The Effect of Different Pre-Surface Finishing Method on the Aluminium Anodization of the 6XXX Series Alloy

In this study, the effect of different pre-surface finishing method on the aluminium anodization was investigated for AA 6063 alloy. Within the scope of pre-surface finishing method which is acidic solution concentrations and process time were determined. Acidic solution was determined by using hydrofluoric acid (HF) and nitric acid (HNO3). Also Gresoff LIM-5 LV chemical was used with different concentrations and process time for degreasing process. The etching effect of acidic solution on aluminium samples was investigated. The optimal etching behaviour was obtained with 1.0% concentration of HF and 3.2% concentration of HNO3 at 10 minutes process time. Also optimal surface properties were observed with 1.0% concentration of Gresoff LIM-5 LV at 12 minutes process time. Then anodic oxidation was performed by using 180 g / L sulfuric acid (H2SO4) and 18 volt (V). Surface morphology of the final aluminium profiles were examined with SEM analysis, Roughness, Gloss and Thickness tests.
