Abstract

The sol-gel process, using aqueous solutions, is used for dip coating onto substrates of 316L stainless steel. A suitable coating of LiCoO2 is achieved by varying the thickness and heat treating at 650°C for 3 h. Thermal analysis, X-ray diffraction analysis and SEM are carried out to characterize the microstructure of the coatings. The results show that the coating transforms an amorphous gel to crystalline phases above 350°C, and show a porous structure. The phase transition mechanism is discussed.
