Solution Precursor Plasma Spraying SPPS

To understand the SPPS deposition process, key diagnostic and characterisation experiments were performed on Y203-stabilised Zr02 coatings (Bhatia et al., 2002). The results from these experiments show that there are multiple pathways 

Nanocrystalline hydroxyapatite coatings were deposited by plasma spraying of sols formed from various precursor solutions by Coyle et al. (2007). The coatings were designed to possess improved resorption in vivo and thus reduced the risk of forming larger debris particles that may give rise to particle disease .

Solution-Precursor Plasma Spray (SPPS) process... 

Recently, some innovative plasma-spray techniques have been employed to produce TBCs with lower thermal conductivities and more durable performance. The solution precursor plasma spray (SPPS) has been exploited to deposit TBCs, in which an aqueous chemical precursor feedstock, rather than YSZ powders, is injected into plasma jet [25,26]. The lack of large-scale splat boundaries effectively toughens the TBCs, making SPPS TBCs highly durable relative to APS TBCs.
