Abstract

A Mo-B-C nanostructured coating was prepared on WC-Co hard-metal substrate by magnetron sputtering. The details of microstructure of deposited thin layer as well as elements redistribution caused by subsequent annealing at 1000 °C were studied by several experimental techniques, namely scanning electron microscopy, transmission electron microscopy and glow discharge optical emission spectroscopy. A strong effect of Co diffusion from substrate to the coating was detected resulting in the formation of interlayer at coating/substrate interface.
