Highly-bonding hard material coating system on cubic boron nitride substrates, comprises multi-layer laminated composite introduced on the substrate

摘要

The highly-bonding hard material coating system on cubic boron nitride substrates, comprises multi-layer laminated composite introduced on the substrate. The laminated composite is made of a first ductile metallic layer nearest to the substrate, a second graded transition layer, an adhesive layer and a hard material covering layer.
