Fig. 2 Thermal spray coating. Buildup of a thermal spray coating is a chaotic process. Molten particles spread out and deform (splat) as they strike the substrate, at first keying onto asperities on the substrate surface, then interlocking to one another. Voids can occur if the growing deposit More

Fig. 9 Schematic showing the buildup of a plasma spray coating. Molten particles spread out and splatter as they strike the target, initially locking onto the irregularities of the roughened surface and then interlocking with one another. Voids result as the growing deposit traps air. In some More
