SMT-2267 is a titanium carbo-nitride
coating deposited by the State-of-the-art physical
vapour deposition (PVD) process
SMT-2267 is highly wear resistant and hard
coating providing solutions to lots of applications
like high speed cutting, stamping, punching etc.
SMT-2267 provides higher hardness and lower
co-efficient of friction than titanium nitride (TiN).
Addition of carbon atoms in the TiN FCC crystal
structure enhances wear resistance property and
also reduces friction co-efficient of the coating. The
graded structure improves the impact toughness of SMT-2267 coating that widens the range of its application in various
industries. It is not, however, a replacement for all TiN applications. SMT-2267 is recommended for cutting, punching and
wear applications where moderate temperatures
are generated. SMT-2267 coating displays its
special strengths in tapping and thread forming,
high load punching and metal forming applications.
The coating thickness range is 2-3 µm and can be
tailored as per application
