【 摘 要 】

The coating of metal increases the face value of the plastic and inhibits other properties like conductivity, hardness and lustre. Thus the combination of plastic and metal coating results in a material that is light in weight because of the presence of plastic as the base material and; electrical and thermal conductive because of the presence of metal on the surface. The requirement of such materials is growing day by day. Copper coated plastic has various applications such as in fabrication of printed circuit boards (PCB's) and various automobile parts and in electromagnetic interference shielding. It is important to analyse the tribological aspect of the same in order to broaden its range of application. The present work contains 3D modelling of thermally sprayed copper on ABS plastic and simulation of sliding wear test by pin-on-disc method. The Johnson cook flow stress model is selected for the coating material. Archard's wear model has provided the best results for calculating the wear rate. The results obtained are in good agreement with the experimental values.
