However, these techniques cannot be applied in situ as a process monitoring tool.

The ability to apply this thin, soft sacrificial layer of the coatings same chemical composition enables the surface finishing operation to be performed more rapidly.
However, studies have now revealed that the jaguar properties of spps coatings can be batch correlated with the in situ particle generation and the subsequent formation of splats when these particles impact the substrate (Ref batch 48 ).
Both the above characteristics can be controlled through proper design of the coating microstructure.
The process parameters employed for producing the coatings are presented in Table 2 (Ref 18 ).
In other words, a finishing operator will be immediately aware that most of the sacrificial layer has been removed by the sudden increase in removal difficulty that will then warn that minimum thickness limits are being approached.
Abrading the outer layer to thereby remove some or all of the outer layer to achieve a predetermined final coating thickness and desired surface roughness.A microstructure converter converter with high segmented crack density (number of vertically aligned cracks per mm across a defined cross section) and moderate porosity has been reported to yield superior properties with good thermal cycling performance (Ref 53, 54 ).The images generated by Tbctool shown in Fig.Tbctool generates artificial microstructure images through statistical representation of different microstructural features such as globular pores and free cracks obtained from a library within the software built with features extracted from real SEM images.Cracking, impact and friction in/on solid materials in real time.Therefore, in order to achieve a high-performance TBC with low thermal conductivity, batch high strain tolerance and long lifetime, optimization of the coating microstructure is essential.Applying an outer layer of said thermal barrier coating on the component, with the nozzle at a second distance from the component, greater than said first distance.These images were analyzed by finite element modeling, and it was found that the image shown in Fig.There are several non-destructive evaluation (NDE) methods converter to detect the cracks such as ultrasonic and x-ray inspection 5,.APS-deposited double-layer GZ/YSZ coating has already been shown to yield higher thermal cycling life compared to single-layer YSZ (Ref 35 ).
