通过在液体淬火剂中淬火，尺寸和形状通常会发生变化。这种现象称为畸变，会造成尺寸变化的大散射。造成这一结果的主要原因之一是在淬火过程开始时绝缘蒸汽层的不均匀击穿（莱顿弗罗斯特现象）。在气体中淬火时，不会出现这种现象。这意味着气体淬火除了积极的环境因素外，还具有减少畸变散射的潜力。为了评估由 SAE 52100 和 SAE 5120 钢制成的轴承和齿轮行业的潜在组件，在单室和两室炉中通过气体淬火进行硬化。第一步是改变气体类型和压力，以接收有关正确硬化结果所需条件的信息。第二步是测量工业炉中油气淬火时不同轴承和齿轮类型的变形。本文介绍了这些调查的结果。
By quenching in liquid quenchants changes in dimension and shape arise normally. This phenomenon is called distortion and effects big scatterings of dimensional alterations. One of the main reasons for this result is the non-uniform break down of the insulating vapor layer at the beginning of the quenching process (Leidenfrost phenomenon). During quenching in gases this phenomenon does not appear. This means that gas quenching includes beside positive environmental aspects a potential for the reduction of distortion scatterings. For evaluation of this potential components of bearing and gear industry made from the steels SAE 52100 and SAE 5120 were hardened in a single chamber and a two chamber furnace by gas quenching. In a first step variations of gas type and pressure were done to receive informations about the necessary conditions for a correct hardening result. In a second step distortion of different bearing and gear types were measured for oil and gas quenching in industrial furnaces. This paper presents the results of these investigations.
