@article { , title = {Residual Stress Measurement of Suspension HVOF-Sprayed Alumina Coating via a Hole-Drilling Method}, abstract = {The nature and magnitude of residual stresses in thermal-sprayed coatings determine their lifetime and failure mechanisms. The residual stresses of suspension high-velocity oxy-fuel (SHVOF) thermal sprayed alumina (Al2O3) coating were measured with hole-drilling and x-ray diffraction. The coating is dense and consists of amorphous and two crystalline phases: alpha and gamma. The residual stresses measured by hole-drilling in the Al2O3 coating was − 162 MPa (compression) in the longitudinal direction and − 104 MPa (compression) in the transverse direction. This is due to the peening stress and the high substrate–coating CTE ratio of ~ 2.1. The nature of the residual stress through the coating is related to the microstructure build-up shown from the cross section and the fracture surfaces of the coating.}, doi = {10.1007/s11666-020-01072-z}, eissn = {1544-1016}, issn = {1059-9630}, issue = {6}, journal = {Journal of Thermal Spray Technology}, note = {Need to add volume, issue and pagination.
