Yttria‐stabilized zirconia (YSZ) deposits were prepared by an atmospheric plasma spray (APS) on a stainless‐steel substrate preheated to different temperatures from room temperature to 1100°C. The microstructure of the deposits was characterized from polished and fractured cross sections by scanning...
