Effects of Processing Parameters in the SPPS and to Understand Their Implications and Improvization | Chapter 9 | Contemporary Perspective on Science, Technology and Research Vol. 9

The preliminary investigations have been carried out about the effects of processing parameters in the SPPS and to understand their implications and improving of this process. The thermal spray processes have been using the different kind of powder feed stocks such as for the coating. It has been widely used for various purposes like to protect from corrosion, improve durability and oxidation resistance properties at high temperature and it can reduce the metal service temperature.
 
The Solution Precursor Plasma Spray (SPPS) process has been used for Thermal Barrier Coatings (TBCs). In this work Zirconyle nitrate is used as solution precursor. It has prepared in house for plasma spray. The prepared solution has successfully deposited on the substrate by SPPS process.The deposited coatings were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). SEM observations showed significant effect of processing conditions on the microstructure of YSZ coatings. The prepared solution can be used for the surface coating.
