Study on the Sol-gel to Prepare Al_2O_3·ZrO_2 Ceramic Cating

MA Zheng qing,LI Wen xian,TAN Dun qiang,XIAO Yu de,YU Kun (Deparment of Materials Science and Engineering,Central South University,Changsha 410083,China)  
The Sol gel method was used to prepare the complex ceramic coating of xAl 2O 3·yZrO 2 on stainless steel surface with Al(NO 3) 3?ZrOCl 2 and ethanol.The ijfluence of the preoxidized base,the bath composition and the additive on the coating structure and performance was studied.The results show that the adhesive strength can be greatly improved by preoxidzing the base;The xAl 2O 3·yZrO 2 ceramic coating had a high temperature oxidation resistantce than stainless steel.
