本文阐述经济上能与吸热式气氛渗碳竞争的氮基气氛渗碳法。这种方法是Airco公司研制成功的,它以氮气充入渗碳炉的前室,能在较低费用下达到吸热式气氛渗碳那样的质量与可靠性水平,例如,可获得相同的硬度、渗层深度、碳浓度梯度与显微组织特征等。本文着重介绍吸热式气氛与氮基渗碳气氛的成本对比。 This article describes a nitrogen-based carburizing method that economically competes with endothermic carburizing. This method, developed by Airco, fills the chamber of a carburizing furnace with nitrogen and achieves the same level of quality and reliability as endothermic carburizing at a lower cost, for example, with the same hardness , Depth of infiltration layer, carbon concentration gradient and microstructure characteristics. This article focuses on the cost comparison of endothermic atmospheres with nitrogen-based carburizing atmospheres.
