Abstract
The thermal expansion characteristics of overlay coatings is of considerable importance when the coated parts are exposed to thermal cycling. In this study we investigated the thermal cycling behavior of oxide coatings plasma sprayed onto mild steel. Thermal expansion measurements were carried out on Al 2O 3TiO 2 and zirconia coatings under different conditions of coating-substrate adherence and on coatings that were substrate free. A study was initiated of the effects on the expansion coefficient of variations in composition, porosity, heating rate and thermal cycling. In addition, metallographic and acoustic emission methods were employed to examine the compatibility of these oxide coatings with steel substrates under varying conditions.
