摘要
The sol-gel process, sing aqueous solutions, is used for dip coating ontosubstrates of 316L stainless steel. A suitable coating of Li CoO_2 is achieved by varying thethickness and heat treating at 650 deg C for 3 h. Thermal analysis, X-ray diffraction analysis andSEM are carried out to characterize the microstructure of the coatings. The results show that thecoating transforms from an amorphous gel to crystalline phases above 350 deg C, and show a porousstructure. The phase transition mechanism is discussed.
