Ysz-Based Infrared Emissivity Performance of Electroplated Pt Composite Coatings

Abstract

This study aims to examine the infrared emissivity characteristics of electroplated platinum composite coatings derived from yttria-stabilized zirconia (YSZ) ceramic coatings within the temperature range of ambient conditions to 1000 °C. Infrared emissivity tests were performed at temperatures of 25 °C, 600 °C, 800 °C, and 1000 °C, and the infrared emissivity of several coatings at ambient temperature after prolonged oxidation was assessed. The results indicate that the infrared emissivity of the composite coatings increases substantially as the temperature increases. The composite coatings with a YSZ-Al-Pt structure exhibit the least significant trend in infrared emissivity as the temperature increases. In comparison to Ni and Cr, the composite coatings exhibit optimal oxidation resistance and thermal shock resistance when the intermediate layer is composed of Al.
