Bernex™ 13 TiC+Ti(C,N)+TiN

Bernex™ 13

Bernex™ 13 is a multipurpose CVD coating for high-volume machining of metals, especially steels. Its primary feature is the ideal combination of wear resistance and toughness. The combination of TiC and TiCN results in an exceptional rupture strength of the cutting edges at low to medium cutting speeds. TiN as a surface layer optimizes friction-caused wear and the running-in behavior of the tool, due to its low coefficient of friction. Bernex™ 13 is applied by means of CVD at ca. 1000° C and is suited for cemented carbide cutting inserts as well as for high-alloyed, secondary hardened tool steels.
