Tanury TPVD ZrN is a medical grade, wear resistant
coating with high hardness, excellent corrosion resistance and a low coefficient
of friction. TPVD ZrN has been used as a coating for medical and surgical
instruments that may experience corrosion due to contact with bodily fluids
or sterilization solutions. In salt spray corrosion tests, ZrN has improved
the corrosion resistance of stainless steel. It can be deposited with
good adhesion at temperatures as low as 350¡ F. TPVD ZrN can be used as
a decorative coating and in some instances in place of TiN for product
differentiation purposes.
TPVD ZrN has been certified
to be biocompatible based on a series of tests conducted by an independent
biological testing laboratory. The biocompatibilty test include those
typically required by the tripartite protocol for materials which experience
short term body contact.
