Modeling of temperature and residual stress fields resulting from impactingprocess of a molten Ni particle onto a flat substrate

摘要

Several effective numerical techniques, based on finite element analysis, have been developed and computedindependently in this paper. Results are presented describing the impacting process, and the subsequenttemperature and residual stress fields of a molten nickel particle impacting onto a flat substrate. Problems of thistype, especially the prediction of the thermal residual stresses, are of major practical interest in thermal sprayoperations as a pioneering approach.
