Tungsten Carbide Inserts Coating Architecture for Turning Operation (2)

In the turning operation, coatings on the tungsten carbide inserts have been approved to make efforts in  cutting forces reduction and extending the tool life to provide greater productivity. It should be noticed that, if these coating architectures could be well accepted, the tungsten carbide inserts are likely to make some significant cost reductions in this area, and to enable higher turning speeds and lower frictional losses during machining.

However, due to the technology limitation and inherent coating processes shortcomings, it still difficult to balance all the factors and which results, so far no single layer, multi-layer or multicomponent coating has been developed yet to meet satisfactorily meet all these requirements.
