Tool wear has large impact not only on production costs but also on the quality of the final product. Therefore the intensivity of the tool wear should be reduced as much as possible. This leads to the development of new surface- engineering techniques in order to improve their wear resistance. In this paper new duplex treatment consisted of plasma nitriding and gradient multilayer PACVD coating was developed. The improvements of the treated surfaces in terms of wear and corrosion resistance have been analysed and new duplex treatment showed significantly higher wear resistance when compared to non-coated steel. Finaly, new duplex treatment was successfully applied on the moulds.
