Underlying mechanisms of the stress generation in surface coatings

This paper was aimed at providing the underlying thermo-mechanical mechanisms in relation to the residual stresses in surface coatings. Four different topics were involved, namely the analytical model for predicting the residual stress, the accuracy of Stoney's equation, the bifurcation behavior for a coating system, and the optimal design for improving the adhesion of a coating. All these topics were in relation to the curvature and the misfit strain created during the coating deposition process, the material properties and dimensions of the coating and substrate.
