Deposition mechanisms in high velocity suspension spraying: Case study for two bioactive materials

► Deposition mechanisms in high velocity suspension spraying (HVSFS) are studied. ► Splats of tricalcium phosphate and bioactive glass are collected onto glass plates. ► Splats come from molten drops within a definite size range (sprayability window). ► Enhanced deposition efficiency when particle size matches with sprayability window ► Phase composition of splats depends on constituent material and thermal history.
