HARDNESS AND FRATURE TOUGHNE OF PLASMA SPRAYED ZIRCONIA-CERIA-YTTRIA THERMAL BARRIER COATINGS
Several studies have been made during the recent years to evaluate the plasma sprayed yttria partially stabilized zirconia thermal barrier coatings but less attention were undertaken on ceria-yttria stabilized zirconia. In this study, zirconia- 20 wt% ceria-3.6 wt% yttria thermal barrier coatings we...

| description | Several studies have been made during the recent years to evaluate the plasma sprayed
yttria partially stabilized zirconia thermal barrier coatings but less attention were
undertaken on ceria-yttria stabilized zirconia. In this study, zirconia- 20 wt% ceria-3.6
wt% yttria thermal barrier coatings were produced by air plasma spraying deposited on
IN 738 LC superalloy substrate. The objective of this study is to analysis the distribution
of porosity, hardness and fracture toughness on the deposited coatings. Under optimum
plasma spraying conditions, it is dangerous to consider the mean values of hardness and
fracture toughness. The distributions of hardness and fracture toughness are highly
scattered. The Weibull distribution is the main parameter to describe the plasma sprayed
coatings hardness and fracture toughness. |
