Research Abstract	To overcome the disadvantage of poor mechanical strength, metallic and ceramic coatings over plastic surfaces are employed. In this study an attempt was made to coat the metals such as copper (Cu) and nickel (Ni) on plastic substrates using the gas tunnel type plasma spraying. Their microstructure and mechanical properties of these coatings were investigated in various spraying conditions. Metallic coatings such as Cu and Ni were successfully deposited on the PET surface with thicknesses of 150 μm through gas tunnel type plasma spraying.
