Plasma spraying (PS) is the most frequently used coating technique for implants; however, in other industries a cheaper, more efficient process, high-velocity oxy-fuel thermal spraying (HVOF), is in use. This process provides higher purity, denser, more adherent coatings than plasma spraying. The pr
The microstructure of thermal barrier coatings (TBCs) of 7 wt.% Y 2 O 3 stabilized ZrO 2 (7YSZ) deposited using the solution-precursor plasma spray (SPPS) method has: (i) controlled porosity, (ii) vertical cracks, and (iii) lack of large-scale "splat" boundaries. An unusual feature of such SPPS TBCs
