The influence of process variables on vacuum carburizing
- C.I. Hayes, Inc., Downers Grove, IL (United States)
Vacuum carburizing has gained acceptance as an alternative to atmosphere carburizing, particularly in those applications where the case requirements are demanding and/or integration of the carburizing facility with other machine tools is required. With this acceptance comes the need to better understand the influence of the various process variables. This paper concludes a two year study of this need and summarizes all work done to evaluate the influence of pulse/pump parameters; gas composition; furnace partial pressure; gas inlet frequency; and gas inlet pressure on the carburizing process. Statistical analysis methods using both L8 (Part One) and L16 (Part Two) full factorial experiments have been conducted and used to determine the extent of the influence of each process variable on carburizing standard and complex part geometry of production loads. This paper reviews the findings of these experiments for the carburizing temperature of 955 C (1,750 F).
