YSZ molten droplets created by plasma spraying were deposited on the YSZ substratepreheated to different temperature from 75oC to 1000oC. The results showed that there is little changein crack spacing when substrate temperature is less than about 740oC, and a significant increase incrack spacing from 3.54 μm at 740oC to 10.91 μm at 1000oC was observed. A simple qualitativemodel was proposed on the basis of the origin of thermal stresses to explain the influence of substrateinitial temperature on crack density characterized by crack spacing. The analysis indicates that theresults can be ascribed to the changes in tensile stress and splat/substrate adhesion resulting fromchanges of substrate initial temperature
