摘　　要：A novel surface technique has been developed to produce ZrO2 and ZrO2-Y2O3 coatings on the surface of alloys by using double pulsed plasma arc to react with a so-lution film containing nano-oxide particles. These coatings exhibit smooth surface and excellent adhesion with substrate. The morphologies of the ceramic coatings and phases were analyzed. It was shown that the oxidation resistance of 18-8 stainless steel was markedly improved by applying ZrO2 and ZrO2-Y2O3 coatings.A novel surface technique has been developed to produce ZrO2 and ZrO2-Y2O3 coatings on the surface of alloys by using double pulsed plasma arc to react with a so-lution film containing nano-oxide particles.
