Abstract: High Velocity Oxy-Fuel (HVOF) spraying of Inconel-718 powders on mild steel sheets is carried out. Three-point bending tests are carried out to examine the mechanical properties of the coating. Stress fields developed during the tests are simulated using Finite Element Method (FEM). ANSYS package is used to predict the stress field. Three- and two-dimensional modeling of the coating and substrate material are considered and the predictions of load–displacement characteristics are compared with the experimental results. Since two-dimensional predictions agree well with the experimental data, two-dimensional model is employed in the simulations. Consequently, crack initiation and propagation at coating and substrate material interface occurring may be determined, similarly above steps were carried out for different thickness and for different loading conditions of coating materials.
