Structural Properties, Modeling and Optimization of Tribological Behaviors of Plasma Sprayed Ceramic Coatings

Abstract:

This study used Taguchi plasma-sprayed experiments to determine the surface wear-resistant performance optimization of yttria partially stabilized zirconia (ZrO2/8Y2O3) coatings. Eight control factors based on L18 arrays were conducted and the wear-resistant properties of coatings were evaluated in the experiments. Based on analysis of variance, the optimal settings have been identified, and response surface methodology is utilized. Further, the contour nature of the quadric function is conducted to validate the tests in the Taguchi designed experiments. The experimental results obtained show that using an experimental design strategy with the proposed quadric model is useful not only for predicted optimal process parameters to achieve a desired quality but also for process optimization. Several response plots were generated to examine parameter effects on the response profiles. In addition, microstructures of the worn surface were examined, revealing a dense texture and highly anisotropic properties in the coatings with high anti-wear behavior.
