Summary
Residual stresses are an important issue for the manufacturing and operation performance of thermally coated layer composites. The quality of the composites with regard to the residual stresses, microstructure and mechanical properties can widely be varied by tuning the spray parameters like simultaneous process cooling, substrate preheating or energy supply. The correlation between composite quality and spray parameters has to be known to optimize the spraying process and finally the operation behaviour of the composites. A key requirement for an optimized and repeatable manufacturing process as well as for reproducible high quality composites is the possibility to measure the residual stresses with reliable measurement tools. This study describes measurement features of the high speed circular microhole drilling method, the FEM-calculation of calibration curves and reproducibility and reliability investigations of the measured residual stress results.
