Nitrex Metal received an order from a European manufacturer of hard-rock drilling tools for a gas nitrocarburizing turnkey installation, complete with furnace, control system and technology. The selected NITREG®-C potential-controlled nitrocarburizing technology and customized process recipes meet the company’s technological requirements for tool performance and reliability, while the ONC® in-process post-nitrocarburizing oxidation provides additional corrosion resistance to maximize tool longevity. The combination of these treatments over the previously used salt-bath nitriding method will optimize the performance and cost while achieving greater environmental compliance.
