Abstract
The present paper used an Eulerian model to study effects of the substrate material and the substrate temperature on the particle deformation behaviour in cold spraying dissimilar particle/substrate combinations. Results show that the deformation pattern of the particle presents a spreading and penetration way for soft/hard and hard/soft particle/substrate material combinations respectively. In addition, preheating the substrate can achieve a coordinated deformation pattern for the soft/hard particle/substrate material combination and a maximum steady PEEQ ranging in 3·2-3·5 in the present study.
