Abstract
In order to test the propensity to form soot in the vacuum carburizing method, the pyrolysis of acetylene, methane, propane, and cyclohexane as vacuum carburizing media was studied at typical operating conditions of vacuum carburizing. Under the test conditions, methane is the most stable media and propane and cyclohexane are the easiest to decompose. The propensity to form soot in the vacuum carburizing furnace varies, then, according to the media. The pyrolysis of the hydrocarbons was also calculated by means of a reaction kinetics model with a software package for combustion analysis. This model includes Polycyclic Aromatic Hydrocarbons (PAH) which are known as precursors to soot formation and growth. The calculated variation of the concentration of the pyrolyzed hydrocarbons with time agreed qualitatively with the experimental results.
