CA Plant Now Offers Vacuum Carburizing

51ÁÔÆæ of CA recently added Low Pressure Vacuum Carburizing (LPVC) to their vacuum heat treating, air tempering, and cryogenic services.
Carburizing is a common form of surface treatment for critical steel parts subjected to the most demanding performance requirements. The process is performed to significantly increase the surface hardness/strength of steel parts for improved friction and wear.
LPVC offers a level of precision not available in conventional atmospheric equipment by incorporating state-of-the-art microprocessors for cycle control, optimization, and repeatability. This provides the ability to pre-program critical cycle parameters, including the multiple pre-determined boost/diffuse pulsing and cool down sequences.  Performing LVPC in a vacuum furnace eliminates oxygen during processing which completely prevents the occurrence of intergranular oxidation (IGO) that is inherent in atmospheric carburizing.  This produces a high integrity case and eliminates the need to remove IGO, which can drastically reduce the fatigue strength/life of the parts. The prevention of IGO, along with the use of hydrogen gas in the heat-up and carburizing boost stage of the cycle, coupled with the computerized processing controls, provides a process that produces extremely uniform and repeatable case depths and microstructures.   Clean parts and less distortion minimizes post process finishing operations, thus reducing costs.
