碩士 === 龍華科技大學 === 工程技術研究所 === 100 === This study is the use of hard anodizing surface treatment technology to pre-treatment of aluminum alloy, aluminum alloy to improve its surface appearance(showing light-colored), the experiments were prepared with different concentrations of sulfuric acid solution as electrolyte, the control temperature is below 15ﾟC change in the way of constant current experiment, experiment with different concentrations of organic additives in the electrolyte, the measured coating thickness and hardness of the specimen after the experiment, the amount of the specimen after the experiment to measure the coating thickness and hardness, and using the SEM (Field Emission Scanning Electron Microscopy) and EDS (Energy Dispersive Spectrometer) to observe the surface morphology and structural properties of the specimen, finally, compare the nature of the specimen surface. The results show, lower the temperature and sulfuric acid electrolyte concentrations ranged between 10-15% can get a good look (showing light-colored) and coating thickness and hardness.
