Description
Summary:Chemical metallisation of cubic boron nitride (cBN) in solutions containing copper ions has been achieved in order to use the metallised hard material for its inclusion in composite materials. It was found to be appropriate to work with smaller fractions of cBN grains, in order to avoid an uneconomically long period of electroless copper plating. The possibility of obtaining composite materials by copper chemical plating with included dispersed particles of cubic beta- and alpha hexagonal boron nitride with a grain size range of 50-80 μm for cBN and 1-5 μm respectively for hexagonal boron nitride on flexible materials of the pressed polyethylene terephthalate textile was shown.
