Optimized Corrosion Resistant Bearing and Gear Steel Thermal Processing

New, patented highly advanced thermo-chemical processing (LINTERPROCESS™) and heat-treatment (LINHEAT™) technologies, presented in this proposal, were developed by SANOVA to address and solve metal and alloy performance issues described in this SBIR. Based on these innovative technologies, SANOVA will design treatment process which creates highly durable protective surface layers on components made from Pyrowear® 675 alloy with superior corrosion resistance and other strong mechanical properties. Pyrowear® 675 is one of the more promising relatively new materials being studied for use in bearing and gear manufacturing. But achieving adequate corrosion resistance on the surface of this alloy, while maintaining required mechanical properties and microstructure, proved to be a formidable challenge for traditional heat-treatment technologies. SANOVA’s LINTERPROCESS™ and LINHEAT™ technologies have a distinct advantage over traditional furnace-based treatment processes due to combination of specially generated and applied highly effective active media and precise control of treatment parameters, and are able to produce desired mechanical performance, microstructure and compression stresses of Pyrowear® 675 surface layer, while keeping chromium levels adequate to exhibit strong corrosion resistance. LINTERPROCESS™ and LINHEAT™ technologies are unique and offer important performance advantages and cost savings over traditional heat-treatment technologies. They produce highest-quality results in shortest treatment durations.
