摘要：

Deformation and fracture of individual micrometre-sized Ni/Au coated polymer particles have been studied by a nanoindentation-based flat punch method. A wide range of test conditions has been applied to deform the coated and the uncoated particles. The compression induced cracking of the Ni/Au coating and delamination between the metal coating and the polymer core have been investigated and provide insight into the effect of nanoscale metal coating on the deformation capacity and fracture process of the particles. A three-stage deformation and fracture behaviour of the particles have been identified. The results are essential for the design of metal coated polymer particles for industrial applications.
