Experimental Study on Vacuum Carburizing Process for Low

Feb 01, 2014 · The vacuum carburizing process can improve the quality of gears and extend the service life. In this article, a complete heat-treatment process for 20Cr2Ni4A, with carburizing, tempering, quenching and cryogenic steps involved, was proposed. A numerical method was employed to design the carburizing step. Experimental Study on Vacuum Carburizing Process for Low DOI:10.1007/s11665-013-0762-1 Corpus ID:137622444.

Carburizing atmosphere in the saturation stage is delivered to the sample surface in a continuous manner. 2. Composition of carburizing atmosphere remains constant throughout the process. 3. Carbon atoms are released as a result of catalytic interaction between the atmosphere and the carburized surface. 4.

In vacuum carburizing, a small quality of hydrocarbon gas (i.e., C 2 H 2, C 6 H 12) is added to a vacuum furnace. The addition reacts in the atmosphere and may never reach equilibrium. Also, in some cases soot may form. Therefore, the mass balance boundary condition is not applicable for this process.

The objective of the project is to develop an integrated process for fast, high-temperature carburizing. The new process results in an order of magnitude reduction in cycle time compared to conventional carburizing and represents significant energy savings in addition to a corresponding reduction of scrap associated with distortion free carburizing steels.
