Modeling of Temperature and Residual Stress Fields Resulting from Impacting Process of a Molten Ni Particle onto a Flat Substrate

摘要

Several effective numerical techniques,based on a finite element analysis,have been developed and computed independently.Results are presented describing the impacting process,and the subsequent temperature and residual stress fields of a molten nickel particle impacting onto a flat substrate.Problems of this type,especially the prediction of the thermal residual stresses,are of major practical interest in thermal spray operations as a pioneering approach.
