摘要：In this study, coupled thermal-mechanical analysis of particle impact behavior in cold spraying was conducted for Cu by using ABAQUS program. Some important aspects on particle initial temperature in cold spraying were examined. The results show that initial temperature of particle takes an important role in 3D simulated results. As the initial tempe-rature rising, compression ratio of the particle increases gradually, critical velocity decreases, but depth of the pit charges little. Furthermore, particle initial temperature has some influence on interface temperature rising and the maximum temperature did not occur at the centre point of initial impact. (C) 2011 Published B.V.
