초록
Plasma electrolyte oxidation (PEO) is a kind of anodization, in which a very high voltage or current is applied to a metal substrate in various electrolytes, allowing distinctly thick thickness of the oxide film with outstanding film properties, such as a good corrosion resistance, mechanical strength, thermal stability, and excellent adhesion to a substrate. Herein, we tried to find the optimal pretreatment conditions among commercially available solutions in order to produce PEO anodizing at relatively low voltage. We characterized the surface morphologies of the sample by scanning electron microscope (SEM), atomic force microscopy (AFM), and investigated color parameters of the pretreated surface of Ti by spectrophotometer.
