In the present work, SS304 material has been taken as the substrate for the in-house prepared solution precursor deposition for preliminary process optimisation. An L16 orthogonal array is used in the Taguchi optimal method for segregating parameters for better optimal results. Microstructures with XRD as a part of non-destructive testing methods had been used to check the structural values with thermal impact and elements study. It shows that the deposition of coating is good even at optimum parameters. At high temperatures, grain development and pore closure reduce the porosity of ceramic coatings. The deposition of thickness is increasing with increasing power. Medium raster speed and spray distance of 60 mm and 80 mm are found to be good for thickness deposition. SPPS coatings contain unique characteristic features such as verticle cracks, symmetric fine porous structure, and splats are smaller.
