Deterioration of Thermal Barrier Coated Turbine Blades by Erosion

Table 3

Computed overall blades and maximum local TBC erosion rates on the commercial turbine and the NASA-designed turbine.

Turbine	Particle radial loading % span	Maximum local erosion rate (mg/g/cm^2)	Overall blade erosion rate (mg/g)
			Stator	Rotor
Commercial turbine	5%	72.94 (Rotor suction side)	0.78	0.93
	100%	31.16 (Stator suction side)	0.83	0.87
NASA turbine	5%	60.21 (Stator suction side)	1.50	0.88
	100%	20.43 (Stator suction side)	0.89	0.73
