Abstract: Using plasma spraying, ceramic coating (AL2O3) is sprayed on the inner wall of hydraulic valve. The mathematical model of the flow path of hydraulic valve, ceramic coating and base are set up, at the same time, computer simulation is also processed. The stress profile of all layers can be got. These results lay a foundation for designing and studying ceramic hydraulic valve.

Key words: Base, Ceramic coating, Plasma spraying, Stress profile
