Solution precursor plasma spraying (SPPS) is a process capable of depositing coatings of almost anycomposition by injecting solutions of precursor salts corresponding to the desired coating composition into a DC-arc plasma. The rapid formation of the solid from the solution results in extremely fine crystallite sizes, typically on the order of 20-30 nm. Coating structures can range from extremely high porosities to nearly completely dense. However, a number of complex phenomena are involved and significant challenges exist in understanding and controlling the process in order to be able to reliably deposit coatings of the desired structure, composition, and properties.

溶液前驱体等离子喷涂(SPPS)是一种通过将与所需涂层成分相对应的前驱体盐的溶液注入到直流电弧等离子体中来沉积几乎任何成分的涂层的过程。从溶液中快速形成的固体导致了极细的微晶尺寸，通常在20-30纳米量级。涂层结构的范围可以从极高的孔隙率到几乎完全致密。然而，这涉及到许多复杂的现象，在理解和控制该过程以便能够可靠地沉积具有所需结构、成分和性能的涂层方面存在重大挑战。
