Overview
•Nitron™ O and Nitron™ 100 duplex processes combine Wallwork Cambridge’s state-of-art diffusion hardening processes with PVD coatings, all in a single cycle. The diffusion-hardened layer provides exceptional load support for the subsequent PVD coating, further enhancing its wear resistant properties. This process can be applied to steels and titanium alloys. Nitron™ 100 with titanium nitride on titanium alloys is an excellent alternative to steels to promote weight-saving, and the coating prevents galling of mating surfaces.
