    摘要: The process includes heating of steel alloy parts in the presence of hydrogen prior to introduction of, for example, carburizing gas, preferably acetylene, in the presence of a diluent carrier gas. The process uses a continuous cycle involving only one carburizing (boost) step and one diffusion step, and high velocity gas quenching. The process is advantageously carried out in a unique, versatile vacuum furnace (also having high internal pressure capability) that provides very high velocity, continuous flow gas quenching, and a furnace design, including a long, low profile work zone configuration and quench gas recirculation equipment and flow pattern that facilitates high velocity gas flow. The entire process is accomplished in a single self-contained chamber of the furnace.
