heal.abstract	Thermal spray coatings are used to enhance the wear, corrosion or thermal capabilities of a surface as well as to rebuild worn or damaged surfaces. In thermal spraying there are various individual and fundamental stages. The flattening process of the individual molten droplets is one of the most critical because the coating quality depends on the deposition of individual splats. Fine powder of aluminium bronze was plasma sprayed (APS) onto stainless steel substrates (SS304L), and the effect of substrate temperature in combination with its surface roughness on splat characteristics were investigated. The substrate temperature varied from 25 to 270°C. Three different ranges of surface roughness were used to examine the substrate roughness effect on the morphology of single splats: smooth substrates with Ra from ∼0.01 to 0.03 μm, grit blasted substrates with Ra from ∼1.89 to 2.43 μm and grit blasted substrates with Ra from ∼4.36 to 4.98 μm. An atomic force microscope (AFM), a scanning electron microscope (SEM) equipped with EDS system and electron probe microanalysis, were used in order to study the morphology and chemical composition of the splats. © ASM International.	en
