| Abstract: |
Suspension spraying of ceramics has become a highly innovative field in recent years. The first industrial use of SPS has been in the field of thermal barrier coating application; where the potential of high performance strain tolerant coatings has driven industrial adoption. However, suspension spraying also has the potential to be utilized in several other fields where other ceramic coating types are required.
Suspension thermal spray processes are able to produce a greater variety of microstructure types than traditional thermal spray processes. From columnar to segmented coatings; from highly porous structures to highly dense coating layers. Suspension spray processes are far more sensitive to feedstock parameters than powder processes. While a number of coating types can be achieved through process parameter manipulation alone; suspensions require tailored properties tied to process parameter selection and final coating application in order to reach their full potential.
In this paper, the influence of a number of suspension and spray process parameters on the resulting coating microstructures will be presented. Furthermore, some possible suspension spray routes to the manufacture of dense, porous or columnar microstructures for various applications will be discussed.
