This research presents a developed simple analytical model to estimate the residual stress state and its magnitude in plasma sprayed coating based on the Vickers instrumented indentation results. By means of energy method during a Vickers indentation cycle, it is convenient to compute the stress state and its magnitude without any comparison of load-displacement curves of stress-free reference material. Computed results show that the residual stress in plasma sprayed Al-Si coating mainly ranges between 23-32 MPa in tensile state, which is consistent with the measurement of residual stress in as-sprayed NiCrAlY coating using neutron diffraction.
