The thermo-mechanical response of coated and uncoated forgings during warm water quench is investigated using experimental and FE modeling techniques. Two coating application methods are examined: in the first method, the forging surface is fully coated, while in the second one, the part is partially coated at selected sections of the workpiece. The thermal response during quench is recorded at various locations of the forgings and residual stresses are obtained using the hole drilling method. The study demonstrates that the coating applications proposed herein significantly enhance the surface heat removal rates during quenching and therefore offer the potential to increase mechanical properties. Based on the results, it is also concluded that no significant differences exist between the thermal responses of the partially and fully coated forgings.
