Stresses in plasma-sprayed Cr2O3 coatings measured by neutron diffraction
Abstract
Results of stress measurements in plasma-sprayed coatings obtained by X-ray-diffraction measurements are often ambiguous and difficult to interpret. The neutron-diffraction method was used to determine the residual and applied stresses during four-point bending and compared with results obtained previously by X-ray diffraction. The volume- and lattice-effective Young's modulus was calculated from applied force and lattice deformation, respectively. The obtained results are discussed from the point of view of the behavior of cracks during tensile and compressive loading.
