　　This paper studies the effects of Zn additions on the deposition behavior of Co in oxide films in the simulated PWR primary water environment at 315℃.304 stainless steel was soaked in high temperature solution with Co additions to form the oxide films,then put into solution with Zn additions for corrosion experiments.The SEM and XPS show that after exposed in Zn solutions,the oxide films become more compact and Zn additions displace the Co deposited in the oxide films.
