Bernex™ 13 TiN-TiC-TiN

Traditional CVD Coating for use in metalforming applications

High hardness, toughness, and wear resistance make Bernex™ 13 a versatile product for open tolerance tooling used in light to medium metal forming applications. In addition, the toughness under impact loading makes Bernex™ 13 an excellent product for open tolerance tooling used in cold forging and fastener trim die applications.

Since Bernex™ 13 is deposited by means of the CVD process, they can be deposited onto tools with small openings, complex geometries and long aspect ratios (> 1:1). This capability makes it a viable solution for wire drawing, warm and hot extrusion, and some plastic molding injection nozzle applications.  Bernex™ 13 is an excellent choice for ceramic or non steel tool materials in order to promote superior coating adhesion.

Bernex™ 13 is deposited at 1000 °C. Therefore it is only recommended for tool materials compatible with the CVD process. In addition, dimensional change will occur on tool steel materials coated with Bernex™ 13. Therefore, sufficient dimensional tolerances are required to accommodate the expected dimensional change.
