Suspension Plasma Spray
Encyclopedia
In materials engineering, suspension plasma spray (SPS) is a form of plasma spraying where the ceramic feedstock is dispersed in a liquid suspension
before being injected into the plasma jet.
By suspending powder in a fluid, normal feeding problems are circumvented, allowing the deposition of finer microstructures through the use of finer powders. See for a detailed review of the technology.
Suspension (chemistry)
In chemistry, a suspension is a heterogeneous fluid containing solid particles that are sufficiently large for sedimentation. Usually they must be larger than 1 micrometer. The internal phase is dispersed throughout the external phase through mechanical agitation, with the use of certain...
