A residual stresses numerical simulation and the relevant thermal-mechanical mapping relationship of Fe-based coatings

Publication date: June 2019Source: Results in Physics, Volume 13Author(s): Haoliang Tian, Changliang Wang, Mengqiu Guo, Zhihui Tang, Hui Tong, Xinkun Wang, Shicheng Wei, Binshi XuAbstractResidual stresses model comprehensively considers the three main sources of residual stress during the coating deposition process: quenching stress, thermal stress and phase transformation-induced stress. With the deposited layer temperature, coating thickness, number of deposited layers and relevant workpiece dimensions as the input, the model can easily calculate the final residual stress distribution in the coating. Moreover, the thermal–mechanical behavior during the coating deposition process was revealed through experimental and theoretical analysis of coatings. The results showed that the coating fabricated within the range of 65.2–122.5 °C have relatively low residual stresses, ensuring relatively high service reliability.Graphical abstract
